Answer:
x = 34
Step-by-step explanation:
5(x + 7) = 6x + 1
Distributive property
5x + 35 = 6x + 1
Subtract 5x from both sides
35 = x + 1
Subtract 1 from both sides
34 = x

Find the fraction that is halfway between 1/4 and 2/7?
Answer:
15/56
Step-by-step explanation:
To get the answer, you find the least common denominator of 4 and 7 which is 28. 1/4 is equal to 7/28. 2/7 is equal to 8/28. if you subtract 7/28 from 8/28, you get one twenty-eighth (1/28). Half of 1/28 is 1/56. To add 1/56 and 7/28, multiply the numerator and denominator of 7/28 by 2. You will get 14/56. Add 14/56 and 1/56 and the answer is 15/56. I'm pretty sure this is the answer. Thanks!
slope intercept form and standard form
Answer:
First Equation:
Slope Intercept Form: y=-1/2x+6
Standard Form: -1/2x+6
Second Equation:
Slope Intercept Form: y=1x-3 OR y=x-3
Standard Form: 1x-3 OR x-3
Step-by-step explanation:
We can just solve the equation by using the inequalities method.
First Equation:
y - 4 = - 1/2(x - 4)
y - 4= - 1/2x + 2
y = - 1/2x + 6
Second Equation:
y + 7 = 1/3(3x + 12)
y + 7 = 1x + 4
y = 1x - 3

Find the 38th term.
Answer:
175
Step-by-step explanation:
1)Firstly you have to find the nth term of the sequence -10,-5,0,5. There a gap or +5 in each term meaning it's 5n. If we substitute n with the number it is in the sequence we can find out the next part of the nth term. For example the first number of the sequence is -10 meaning 5n+x = -10. We repleace n with the 1 since it is the first number in the sequence and we get 5+x = -10. In order to find x by itself we -5 from both sides and we get x =-15. Now we know the nth term of -10,-5,0,5 is 5n-15
2) Now that the hard part is out of the way the rest is simple. N simply reprents the term the number is in. If we want to find out the 38th term we replace n with 38. We get 5x38-15 = 175

Answer:
x = 12
Step-by-step explanation:
Step 1: Add 9 to both sides.
[tex]7x - 9 + 9 = 75 + 9[/tex] [tex]7x = 84[/tex]Step 2: Divide both sides by 7.
[tex]\frac{7x}{7} = \frac{84}{7}[/tex] [tex]x = 12[/tex]Step 3: Check if solution is correct.
[tex]7(12) - 9 = 75[/tex] [tex]84 - 9 = 75[/tex] [tex]75 = 75[/tex]Therefore, x = 12.
Answer:
x = 12
Step-by-step explanation:
This is a multi-step equation.
The first thing we can do is add 9 to both sides, eliminating the -9 from the left side of the equation. Now we have 7x = 84.
You can divide 84 over 7x to get a total of x =12.

3+2x-y=0
-3-7y=10x
Answer: x=-1 y=1
Step-by-step explanation:
solve y in 3+2x-y=0
y=3+2x
sub y=3+2x into -3 -7y=10x
-14x- 24= 10x
solve x in -14x-24=10x
x= -1
sub x= -1 into y =3+2x
y=1
so therefore x= -1 and y=1

The price of Stock A at 9 AM WAS $12.24. Since then, the price has been increasing at
the rate of $0.11 each hour. At noon the price of Stock B was $12.74. It begins to decrease at the
rate of $0.15 each hour. If the two rates continue, in how many hours will the prices of the two
stocks be the same?
Answer:
Step-by-step explanation:
t is the number of hours
12.24+0.11t = 12.74-0.15t
0.11t + 0.15t = 12.74 - 12.24
0.26t = 0.5
t= 0.5/0.26
t= 1.92 hours
approx to 2 hours

[tex] = 40\%[/tex]
40℅ of the students likes to play tennis
hope this helps you
Answer:
40% Use the ratio method
Step-by-step explanation:
Since
10 : 25 = X : 100
Then we know
10/25 = X/100
Multiplying both sides by 100 cancels on the right
100 × (10/25) = (X/100) × 100
100 × (10/25) = X
Then solving for X
X = 100 × (10/25)
X = 40
Therefore
10 : 25 = 40 : 100

Answer:
∠C = 122° and ∠D = 80°
Step-by-step explanation:
This is a cyclic quadrilateral.
Definition: A cyclic quadrilateral is a quadrilateral (a four-sided two-dimensional shape) drawn inside a circle. Every vertex of the quadrilateral must touch the circumference of the circle.
The opposite angles in a cyclic quadrilateral add up to 180°.
Therefore, ∠A + ∠C = 180° and ∠B + ∠D = 180°
To find the value of ∠C:
∠A + ∠C = 180
∠C = 180 - ∠A
∠C = 180 - 58
∠C = 122°
To find the value of ∠D, first find the value of y:
∠B + ∠D = 180
(3y + 4) + (2y + 16) = 180
5y + 20 = 180
5y = 180 - 20 = 160
y = 160 ÷ 5 = 32
Therefore, y = 32
To find ∠D, substitute found value of y into the expression for ∠D:
∠D = 2y + 16
∠D = 2 x 32 + 16
∠D = 80°

Sofia leans a 28-foot ladder against a wall so that it forms an angle of 67° with the ground. How high up the wall does the ladder reach? Round your answer to the nearest hundredth of a foot if necessary.
Using the slope concept, it is found that the ladder reaches a height of 65.96 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change.
It's also the tangent of the angle of depression.
In this problem:
The vertical change is the height that we want to find.The horizontal change is the ladder of 28 feet.The angle is of 67º.Hence:
[tex]\tan{67^\circ} = \frac{h}{28}[/tex]
[tex]h = 28\tan{67^\circ}[/tex]
[tex]h = 65.96[/tex]
The ladder reaches a height of 65.96 feet.

Solve by Factoring (4m +2 )(3m - 9)= 0
i think i know but looking at peoples answer now i am reconsidering my choices but anyway good luck i think u should use the other guy solution but anyway have a good day :>
Explanation:
The equation is already factored for us (well nearly so).
Set each piece equal to zero. Refer to the zero product property.
4m+2 = 0 solves to m = -1/2. Subtract 2 from both sides, then divide by 4 to get m = -2/4 = -1/2.3m-9 = 0 solves to m = 3. You add 9 to both sides, then divide by 3 to isolate m.The two roots are -1/2 and 3. If you were to substitute either value into the equation, then you should get 0 on both sides after simplifying.
