Find the value of x that makes m || n
(2x+20) 3x
Answer:
x = 20
Step-by-step explanation:
For the lines to be parallel, then (3x + 20) and (3x) are alternate angles and congruent, thus
3x = 2x + 20 ( subtract 2x from both sides )
x = 20
Given the expression below and based on the values that are given, what will the sign of the product be? -4*(-8/9)*2.78*(1 1/3)*(-2/5)*(-6.2)*(0.2873)*(3 1/11)* A
Answer:
The sign on the end result is +
Step-by-step explanation:
Given
[tex]-4*(-8/9)*2.78*(1\ 1/3)*(-2/5)*(-6.2)*(0.2873)*(3\ 1/11)[/tex]
Required
Determine the sign of the result
To do this, we simply write out the product of the sign of individual digit.
[tex]-4*(-8/9)*2.78*(1\ 1/3)*(-2/5)*(-6.2)*(0.2873)*(3\ 1/11)[/tex] becomes
[tex]- * - * + * + * - * -* + * +[/tex]
Group the product in 2's
[tex](- * -) *( + * +) *( - * -)* (+ * +)[/tex]
As a general rule:
[tex]- * - = +[/tex]
[tex]- * + = -[/tex]
[tex]+ * - = -[/tex]
[tex]+ * + = +[/tex]
Apply this rule on the above;
[tex](- * -) *( + * +) *( - * -)* (+ * +)[/tex] becomes
[tex]+ * + * + * +[/tex]
Group in 2's
[tex](+ * +) * (+ * +)[/tex]
Apply the rule
[tex]+ * +[/tex]
Finally, this gives:
[tex]+[/tex]
Hence, the sign on the end result is +

1. A system of linear equations is shown below as well as the first steps that Raffi is using to solve this system of linear equations by substitution. Choose the statement that best describes how Raffi is progressing toward a solution.
7x+y=4
3x−2y=3
Solution: Solve the first equation to obtain y=−7x+4. Substitute this into the second equation to get 3x−2⋅−7x+4=3.
2. Solve the following system by the substitution method.
2x−y=−4
−5x+3y=14
Answer:
The answer is below
Step-by-step explanation:
1) Below are the linear equations.
7x+y=4 (1)
3x−2y=3 (2)
The above linear equations are a system of equations. The substitution method is a technique for solving systems of linear equations.
Given that:
7x + y = 4
y = 4 - 7x
substitute y = 4 - 7x in equation 2, hence:
3x - 2(4 - 7x) = 3
3x - 8 + 14x = 3
17x = 3 + 8
17x = 11
x = 11/17
Put x = 11/17 in y = 4 - 7x
y = 4 - 7(11/17)
y = -9/17
2) 2x−y=−4 (1)
−5x+3y=14 (2)
From equation 1:
2x−y=−4
y = 2x + 4
Put y = 2x + 4 in equation 2:
-5x + 3(2x + 4) = 14
-5x + 6x + 12 = 14
x + 12 = 14
x = 2
Put x = 2 in y = 2x + 4:
y = 2(2) + 4
y = 8
Answer:
1. Raffi forgot to place the substituted expression in parentheses.
2. (2, 8)
Step-by-step explanation:
If you are taking the Solving Systems With Substitution Quick Check from Connexus here are all of the answers:
1. Solve one linear function in terms of one of its variables.
2. Substitute 3y from the second equation for x in the first equation.
3. Raffi forgot to place the substituted expression in parentheses.
4. Yes, because substituting the given ordered pair yields two true expressions.
5. (2, 8)

Mrs. Williams combined 3 ½ cups of peat moss, 5 ¼ cups of compost , and 6 ¾ cups of fertilizer to make plant food for her roses. She evenly distributed the plant food among 4 rose bushes. How many cups of plant food were used for each rose bush?
Answer:
3 7/8 cups plants food
Step-by-step explanation:
peat moss = 3 ½ cups
compost = 5 ¼ cups
fertilizer = 6 ¾ cups
Total mixture = peat moss + compost + fertilizer
= 3 ½ cups + 5 ¼ cups + 6 ¾ cups
= 7/2 + 21/4 + 27/4
= 14+21+27/4
= 62/4
Total mixture = 62/4 cups
She evenly distributed the plant food among 4 rose bushes
Each rose bush uses = Total mixture / number of rose bushes
= 62/4 ÷ 4
= 62/4 × 1/4
= 62/16
= 3 14/16
= 3 7/8 cups plants food
Each rose bush uses = 3 7/8 cups of plants food

A pet store has three fish tanks, each holding a different volume of water and a different number of fish. Tank A has 5 fishes with a volume of 40 liters. Tank B has 12 fishes with a volume of 100 liters. Tank C has 23 fishes with a volume of 180,000 milliliters. Which tank has the greatest volume per fish?
Answer:
Tank B
Step-by-step explanation:
A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
a) Tank A has 5 fishes with a volume of 40 liters.
Volume per fish = 40 liters/5 fishes
= 8 liters/fish
b) Tank B has 12 fishes with a volume of 100 liters.
Volume per fish = 100 liters/12 fishes
= 8.33 liters/ fish
c) Tank C has 23 fishes with a volume of 180,000 milliliters.
Convert 180,000 milliliters to liters
1 milliliter = 0.001 liter
180,000 milliliters = x
x = 180,000ml × 0.001 l
x = 180 liters
Volume per fish = 180 liters/23 fishes
= 7.8260869565 volume per fish
Approximately = 7.83 liters/fish
Which tank has the greatest volume per fish?
The tank that had the greatest volume per fish is Tank B at 8.33 liters/ fish

Find the value of x in the parallelogram.
Answer:
Since it's a parallelogram, the length of AD and BC are the same.
Hence, [tex]x + 21 = 12x - 1[/tex].
[tex]x + 21 = 12x - 1[/tex]
[tex]12x - x = 21 + 1[/tex]
[tex]11x = 22[/tex]
[tex]x = 2[/tex]
Therefore, x = 2.

For △PQR and △EFD shown, which of the following could be steps to show that the SSS congruence criteria follows from the definition of congruence in terms of rigid motion? Select two correct answers.
A.Translate EFD so that point F maps to point Q.
B. Rotate (Triangle)E'F'D' so that D' E maps to PR.
C. Reflect (Triangle) E"F"D" across PR so that E" F" maps to QR.
D. Translate (triangle) EFD so that point D maps to point P.
E. Rotate (triangle) E'F'D' so that D'F' maps to PQ.
Answer:
Letter B is the answer.
Step-by-step explanation:
B is the answer because you would want to rotate figure EFD to PQR, where line DE would line up with PR.
A is not correct because a translation would not line up the lines or points. Triangle DEF is facing in a different direction as PQR.
C is not correct because it is only being reflected once and the line upon where it is being reflected wouldn't match up with the triangle PQR. EF would not be able to mapped onto line QR because of the line it is being reflected upon.
D is not correct for the same reason as A, which is because a translation would not line up the lines or points. Triangle DEF is facing in a different direction as PQR.
E gets close because of it being rotated, but it is incorrect since line DF wouldn't match up with line PQ. PQ is only congruent to line EF.

Mia discovered that if she takes half her age and adds 3, it produces the same result as taking one-fourth of her age and adding 7. How old is Mia?
Answer:
she would be 16 years old
Step-by-step explanation:
hope this helps!! :D
From the given information we found out that age of Mia is 16 years.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, Mia discovered that if she takes half her age and adds 3,
Assuming Mia's age to be x years.
∴ (1/2)x + 3...(i)
It produces the same result as taking one-fourth of her age and adding 7,
∴ (1/4)x + 7...(ii)
So, (1/2)x + 3 = (1/4)x + 7.
(1/2)x - (1/4)x = 7 - 3.
(1/4)x = 4.
x = 4×4/1.
x = 16.
So, Age of Mia is 16 years.

What determines the pitch of a sound? PLEASE HELP MEH!!
the decibel level
the frequency of vibrations
the amplitude
the medium
Answer:
Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation.

Explain, with at least 2 complete sentences, how to find the slope from a table.
Answer:
Step-by-step explanation:
We know the slope is rise over run. You can also find slope by using the formula (y2-y1)/(x2-x1) where x1, x2, y1 and y2 are points from the table. These points also aren't random and must correspond with each other. Example x1 and y1.
Find the fifth term in the geometric
sequence, given the first term and
the common ratio.
a1 = 2 and r = 3
a5 = [ ?]
The fifth term is 162 in the geometric sequence.
What is geometric sequence?The geometric sequence defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
What is arithmetic sequence?A arithmetic sequence is defined as an arrangement of numbers which is particular order.
The formula to find the general term of an arithmetic sequence is,
aₙ = a₁ + (n-1)d
Given data :
First term of sequence geometric (a₁) = 2
The common ratio of geometric (r) = 3
To determine the fifth term of geometric sequence
Let the fifth term of sequence = a₅
The nth term of a geometric sequence is expressed as :
Tₙ = a₁rⁿ⁻¹
Substitute the values of n = 5, a₁ =2 and r = 3 in the formula,
T₅ = (2)(3)⁵⁻¹
T₅ = (2)(3)⁴
T₅ = (2)(81)
T₅ = 162
