18 divided by 4 =_____ with _____ left over
Answers
Answer:
18 divided by 4 would be 4 with 2 left over
Step-by-step explanation:
4x4 is 16 and to get 18 you have two more.
18 divided by 4 = 4 with 2 left over. This is because 4 can go into 18 4 times (which is 16) and then 2 remains.

Answers
The correct first step to solving the system of equations in the most efficient manner is x = -4y +19.
The given system of equations is;
[tex]\rm 3 x + 2 y = 17\\\\x + 4 y = 19[/tex]
What is the first step to solving an equation?The first step would be to rearrange the variables in the second equation so we have a defined expression for x.
We would want to do this so we could then plug in the defined expression for x into the other equation and solve for the other variable.
x + 4y = 19
Rearrange this by getting the 4y to the other side.
We can get 4y on the other side by subtracting 4y from both sides
x + 4y - 4y = 19 - 4y
x = -4y + 19
Hence, the correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

During the New Year Festive Bonanza, the price of a jacket was reduced by 30%. Find the original price of the jacket when it cost $280 in the sale.
Answers
Answer:
$400
Step-by-step explanation:
The original price of the jacket = 100%
If the jacket was reduced by 30%, then the discounted price of the jacket = 100% - 30% = 70%
Therefore, $280 = 70% of the original price.
70% = 70/100 as a ratio
Using ratios, and letting [tex]x[/tex] be the original price:
280/[tex]x[/tex] = 70/100
Cross multiply: 280 x 100 = 70 x [tex]x[/tex]
28000 = 70[tex]x[/tex]
Divide both sides by 70: 400 = [tex]x[/tex]
Therefore, the original price of the jacket is $400
Alternatively, divide 280 by 70 to get the cost per 1%. Then multiply this by 100 to get the original price (100%):
(280 ÷ 70) x 100 = 400
y = 2x - 5

One interior angle of a regular polygon is 175 degrees. What is the measure of one exterior angle? Step by step (please answer)
Answers
Answer:
Exterior angle = 185°Step-by-step explanation:
We know that:
Interior angle = 175°Total = 360°Solution:
Exterior angle = 360 - 175=> Exterior angle = 185°Hence, the measure of an exterior angle is 185°.
Answer:
5°Step-by-step explanation:
Solution 1Interior angle equation of the n-sided polygon:
180°(n - 2)Since each interior angle is 175, their sum is:
180°(n - 2) = 175°n180n - 360 = 175n5n = 360n = 72The polygon has 72 sides.
We know the sum of exterior angles of a polygon is 360.
Find the measure of each exterior angle:
360°/72 = 5°Solution 2The sum of interior and exterior angles is 180.

So the top right answer choice (x - 10)² = 80 has the same solution as x² - 20x + 20 = 0
Step-by-step explanation:
Let's solve your equation step-by-step.
x² − 20x + 20 = 0
For this equation: a = 1, b = -20, c = 20
1x² + −20x + 20 = 0
Step 1: Use quadratic formula with a = 1, b = -20, c = 20.
x = −b ± √b² − 4ac / 2a
x = −(−20) ± √(−20)² − 4(1)(20) / 2(1)
x = 20 ± √320 / 2
x = 10 + 4√5 or x = 10 − 4√5
Let's try the top right answer choice
(x−10)² = 80
Step 1: Simplify both sides of the equation.
x² − 20x + 100 = 80
Step 2: Subtract 80 from both sides.
x² − 20x + 100 − 80 = 80 − 80
x² − 20x + 20 = 0
For this equation: a = 1, b = -20, c = 20
1x² + −20x + 20 = 0
Step 3: Use quadratic formula with a = 1, b = -20, c = 20.
x = −b ± √b² − 4ac / 2a
x = −(−20) ± √(−20)² − 4(1)(20) / 2(1)
x = 20 ± √320 / 2
x = 10 + 4√5 or x = 10 − 4√5

Describe the relationship among the lengths of the segments formed by the two secants. You may use words and/or an equation.
Suppose CG=4 in., CH=5 in. and GE=6 in. Is it possible to find the length of DH? If so, show how to find the length. If not, explain why not.
Answers
It is possible to find DH based on the stated theorem
Secant-secant rule:This rule states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant.
Mathematically:
(CG+GE)CG = (CH+HD)CHGiven the following parameters
CG=4 in
CH=5 in
GE=6 in
Substitute to check if we can find DH
(4+6)*4 = (5+DH)*5
10*4 = 25 + 5DH
40 - 25 = 5DH
15 = 5DH
DH = 3in
Therefore it is possible to find DH based on the stated theorem

Step-by-step explanation:
The statements that are false about his solution is Elijah needs labels on the points to determine which sides correspond when writing the ratios.
We are given that;
The statement one triangle is a dilation of the other
Now,
He did not know that scale factors can be fractions or decimals greater than zero. He did not know that dilations are proportional and the relationships are multiplicative, not additive. He should have compared the ratios
[tex]$\frac{5}{3}=\frac{10}{6}=\frac{12.5}{7.5}$[/tex] to determine if they are equivalent.
So, the statements that are true about his solution are:
- Elijah did not know that scale factors can be fractions or decimals greater than zero.
- Elijah did not know that dilations are proportional and the relationships are multiplicative, not additive.
- Elijah should have compared the ratios
[tex]\frac{5}{3}=\frac{10}{6}=\frac{12.5}{7.5}[/tex]to determine if they are equivalent.
