Answer:
George's mistake would be:
Instead of 2x + 40, she has made - x + 20.
Step-by-step explanation:
Slope - Intercept Form = y = mx + b
y + 20 = 2(x +20)
y + 20 = 2x + 40
- 20 - 20
----------------------
y = 2x + 20
(Should have been the answer)
BUT,
George's Solving:
y + 20 = 2(x + 20)
y + 20 = -x + 20
George's Mistake would be her miscalculation during her 2nd step. Where instead of distributing 2 to (x + 20), she has changed it to -x + 20, when in reality, it should have been 2x + 40.

a square with an area of 25 in.^2 is plotted on a grid so that the bottom-left corner is at the origin. The side of the square are horizontal and vertical. A reflection over what line maps the square onto itself?
Answer:
Reflection about the vertical line x = 2.5 inches will map the square unto itself
Step-by-step explanation:
The given parameters are;
The area of the square = 25 in²
The orientation of the sides of the square are horizontal and vertical
Therefore, we have;
The area, A, of the square given by the following relation;
A = Side²
A = 25 in²
Therefore;
The area of the square = 25 = side²
The length of the sides of the square = √A = √25 = 5
The length of the sides of the square = 5 inches
The reflection of a figure that maps the figure unto itself is a reflection along the line of symmetry
One of the line of symmetry that divides the square into two similar halves is the vertical straight that passes half way through the horizontal side, which is the point 2.5 inches to the right on the x-axis with the coordinates (2.5, 0)
Therefore, reflection about the line x = 2.5 inches will map the square unto itself.

Answer:
[tex]\frac{114}{13}[/tex] or 8 [tex]\frac{10}{13}[/tex]
Step-by-step explanation:
1) Convert the mixed numbers to improper fractions
3+ [tex]\frac{15}{2}[/tex] ÷ [tex]\frac{13}{10}[/tex]
2) To divide by a fraction, multiply by the reciprocal of that fraction
3+[tex]\frac{15}{2}[/tex] × [tex]\frac{10}{3}[/tex]
3) Reduce the numbers with the greatest common factor 2
3 + 15 ×[tex]\frac{5}{13}[/tex]
4) Calculate the product
3 + [tex]\frac{75}{13}[/tex]
5) Calculate the sum
[tex]\frac{114}{13}[/tex] = 8 [tex]\frac{10}{13}[/tex]

Step-by-step explanation:
Density (g/cm cubed) = Mass (g) / Volume (cm cubed)
So:
Density = 200g / 20cm cubed
Density = 10g/cm cubed

in the group of hundred students68 likes football 60 likes volleyball how many likes only football
Answer:
18 students.
Step-by-step explanation:
Total amount is 100
Take 68 and add to 60 to get 128.
Subtract from both numbers until you get to 50.
68 needs 18 subtracted to get to 50.
60 needs 10 to get to 50.
18 plus 10 is 28, which is the excess.
Here, 18 people like only football.
Answer:
i think 40
if 68 =likes foot ball
&60=likes volley ball
here there are available the students that likes both because 68+60=128 but the students are 100 so the students that likes both are 128-100=28
threfore the students that like only football are 40
cause the 68 likes football & the28 likes only football
so to know how many students likek foot ball evaluate like this (68-28=40)
i hope helps you
Solve the equation for x. -8(x +9) +6= - 66
Answer:
x=0
Step-by-step explanation:
First you would distribute -8 to the x and 9 to get -8x-72
Then you would put that into the rest of the equation for -8x - 72 + 6 = -66
Then you combine like terms and get -8x - 66 = -66
Then add 66 to both sides and get -8x = 0
Then divide both sides by -8 and 0 divided by -8 is 0
Ariel bought a cake and cut it into sections of 1 3to serve 3 people. She now wants to create smaller pieces so that she can serve each person 3 pieces. Create a fraction equal to 1 3that would give everyone the same amount of cake but in 3 pieces.
Answer:
Fraction = ⅓
Step-by-step explanation:
Given.
Sections = 3
Required
What fraction divides the fraction into 3 equal part
Given that there's only one cake and it's for 3 people .
The fraction for each individual is calculated as follows:.
Fraction = ⅓ * 1 cake
Fraction ,= ⅓ of the cake
Hence:
Each individual will get ⅓ of the cake
40 calls in 20 hours=__calls in 10 hours
I have my answer my mom said its right my dad said its wrong what do u smart people think
Answer: 20 calls
Explanation: This is because since 40 is half of 20, you would need to divide by 2 to get 10. If you convert the division to multiplication, 10 * 2 = 20. So, the answer would be 20 calls.

Write an equation that is parallel to 3x−2y=14 and passes through the point (-6, -11) in slope-intercept form.
Answer:
y = 3/2x - 2Step-by-step explanation:
Given line3x - 2y = 14To findParallel line passing through the point (-6, -11)SolutionLet's put the given line into slope-intercept form
3x - 2y = 142y = 3x - 14y = 3/2x - 7Parallel line has same slope, the equation of the parallel line is
y = 3/2x + bFinding y-intercept using the point (-6, -11)
-11 = 3/2*(-6) + b-11= -9 + bb = -2So the line is
y = 3/2x - 23*-6-2*-11=14
-18+22=14

Simplify the expression.
−23(12c−9)+14c =
The simplification of the expression would be equal to -262c +207.
An equation is defined as an expression which shows the relationship between two or more numbers, variables, and a mathematical equation is a statement with two equal sides and an equal sign in between.
We are given the expression as;
−23(12c−9)+14c =
Now ;
-23(12c) -23 * -9 + 14c
Now Apply the distributive property;
2. -276c -23 * -9 + 14c
Then Multiply 12 by -23
-276c + 207 + 14c
Add -276c and 14c
-262c +207
The answer is -262c +207

Selena made pancakes for an all day breakfast fundraiser event she made 132 pancakes in 4 hours Selena used 44 cups of pancake batter to make 132 pancakes if Selena continues to make the same number of pancakes per cup of batter how many cups of batter will Selena use to make an additional 264 pancakes
Answer:
88 cups of batter
Step-by-step explanation:
We are told from the the question: Selena used:
132 pancakes was made from = 44 cups of pancake batter
how many cups of batter will Selena use to make an additional 264 pancakes?
132 pancakes = 44 cups of pancake batter
264 pancakes = ??
Cross Multiply
= 264 × 44/132
= 11616 / 132
= 88 cups of pancake batter.
Therefore, selena would be needing 8( cups of pancake butter to make an additional 264 pancakes.
Answer:
88
