1 Remove parentheses.
-8(c-10)=−c+3
2 Regroup terms.
-8(c-10)=3−c
3 Expand.
-8c+80=3−c
4 Add 8c8c to both sides.
80=3−c+8c
5 Simplify 3-c+8c to 3+7c
80=33+7c
6 Subtract 33 from both sides.
80-3=7c
7 Simplify 80-3 to 77.
77=7c
8 Divide both sides by 7.
77/7 = c
9 Simplify 77/7 to 11.
11=c
10 Switch sides.
c=11

Kennedy had the expression 3(2x-3x+8). She simplified and rewrote the
expression 3(8+x). If any, what was her error?
Answer:
It is -3x+24
Step-by-step explanation:
2x-3x is -x or -1x
It can also be simplified further using multiplication.
3(2x-3x+8)
3(-x+8)
-3x+24

Answer:
Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.
A'(-5, -2.5)B'(2.5, 5)C'(5, -10)Step-by-step explanation:
Given the vertices of ΔABC
A(-2, -1)B(1, 2)C(2, -4)Given that ΔA'B'C' is a dilation of ΔABC with a scale factor of 2.5 and the center of dilation (0, 0).
We know that when the scale factor > 1, then the image is enlarged.
The formula to determine the dilation with a scale factor of 2.5.
P(x, y) → P'(2.5x, 2.5y)
Here, P' is the image of P, and the vertices of the image is dilated by a scale factor of 2.5.
In other words, the vertices of the image can be obtained by multiplying the vertices of the original triangle with 2.5.
Thus,
P(x, y) → P'(2.5x, 2.5y)
A(-2, -1) → P'(2.5(-2), 2.5(-1)) = A'(-5, -2.5)
B(1, 2) → B'(2.5(1), 2.5(2)) = B'(2.5, 5)
C(2, -4) → C'(2.5(2), 2.5(-4)) = C'(5, -10)
Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.
A'(-5, -2.5)B'(2.5, 5)C'(5, -10)Can you please help? I’m tired and I have to work on this

Answer:
The variable 8. Equation is 16 + 12x = 112.
Step-by-step explanation:
We know that she spent $16 dollars on magazines, so we can put it in the equation (16 + x= ?). We also know that the total is $112, so we can also add that (16+ x= 112). We don't know how many books she got, but we do know how much they cost (16 + 12x=112. So that makes the books the variable (X).
To find the variable we need to take out the magazines from the price. 112-16=96. Now we're left with 12x=96. Now all we have to do is divide 96 by 12, which equals 8.

Answer:
-5
Step-by-step explanation:
As, x = - 1
So 2(-1)-3 = - 2 - 3 = - 5
So y = - 5
Mrs. Olive used 1 2/5 quarts of syrup and 5 3/10 quarts of water to make lemonade. How many quarts of lemonade did she make? * A. 6 1/2 B. 6 7/10 C. 7 1/2 D. 8
Answer:
B. 6 7/10
Step-by-step explanation:
We solve the above y by carrying out addition.
The quarts of Lemonade she made is calculated as:
1 2/5 quarts of syrup + 5 3/10 quarts of water
= 1 + 5 + (2/5 + 3/10)
Lowest common denominator = 10
= 6 ( 4 + 3/10)
= 6 7/10 quarts of Lemonade
Mrs Olive made 6 7/10 quarts of Lemonade

A bag contains 1 blue, 2 green, 3 yellow, and 3 red marbles, as shown.Which best describes the complement of choosing a red marble?
choosing a green or blue marble
choosing any marble
choosing a blue, green, or yellow marble
choosing a yellow marble
Answer:
C) choosing a blue, green or yellow marble.
Step-by-step explanation:
The Complement of choosing a red marble means choosing any other marble that isn't red.
From the question , it was said that there were a blue , green, yellow and red marble.
So the Complement of choosing a red marble will be choosing any other marble apart from the red so ,that will be choosing a blue yellow or green marble.

Answer:
D, the Addition Property of Equality
Step-by-step explanation:
This is the Addition Property of Equality. The Addition Property of Equality is, "If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal." In this case, the person added 5 to both sides. The expression is still equal to what is was before. I hope this helps!

Step-by-step explanation:
Frieda paid $132 for groceries for her family. This was 1 1/8 as much as she paid for the previous time she shopped. How much did Freda pay on her previous shopping trip
Answer:
$117.33
Step-by-step explanation:
1 1/8 = 1 + 1/8 = 8/8 + 1/8 = 9/8
She paid 9/8 what she paid the last time.
Let the amount she paid last time equal x.
$132 is 9/8 of x.
9/8 x = 132
8/9 * 9/8 x = 132 * 8/9
x = 117.33
She paid $117.33

Answer:
[tex]y = -\frac{10}{3}x -23[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-9,7)[/tex]
[tex](x_2,y_2) = (-6,-3)[/tex]
Required
Determine the line equation
We start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex](x_1,y_1) = (-9,7)[/tex]
[tex](x_2,y_2) = (-6,-3)[/tex]
So, we have:
[tex]m = \frac{-3- 7}{-6 - (-9)}[/tex]
[tex]m = \frac{-3- 7}{-6 +9}[/tex]
[tex]m = \frac{-10}{3}[/tex]
[tex]m = -\frac{10}{3}[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex] ---- Point slope form of an equation
Where:
[tex]m = -\frac{10}{3}[/tex]
[tex](x_1,y_1) = (-9,7)[/tex]
[tex]y - y_1 = m(x - x_1)[/tex] becomes
[tex]y - 7 = -\frac{10}{3}(x - (-9))[/tex]
[tex]y - 7 = -\frac{10}{3}(x +9)[/tex]
Open bracket:
[tex]y - 7 = -\frac{10}{3}x -\frac{10}{3}*9[/tex]
[tex]y - 7 = -\frac{10}{3}x -10*3[/tex]
[tex]y - 7 = -\frac{10}{3}x -30[/tex]
Collect Like Terms
[tex]y = -\frac{10}{3}x -30 + 7[/tex]
[tex]y = -\frac{10}{3}x -23[/tex]
Hence:
The equation is: [tex]y = -\frac{10}{3}x -23[/tex]
Answer:
y=-10/3x-23

what is the expression in radical form? (5x^3 y^2) 2/8
Answer: (y^{2}x^{3}⋅5)/4
Step-by-step explanation:
Convert to Radical Form
[tex](5x^3y^2)\frac{2}{8}[/tex]
Reduce the expression [tex]\frac{2}{8}[/tex] by cancelling the common factors.
Factor 2 out of 2.
[tex]5x^3y^2\frac{2(1)}{8}[/tex]
Factor 2 out of 8.
[tex]5x^3y^2 \frac{2(1)}{2(4)}[/tex]
Cancel the common factor.
[tex]5x^3y^2 \frac{1}{4}[/tex]
Combine 5 and [tex]\frac{1}{4}[/tex].
[tex]x^3y^2\frac{5}{4}[/tex]
Combine [tex]x^{3}[/tex] and [tex]\frac{5}{4}[/tex] .
[tex]y^2\frac{x^3(5)}{4}[/tex]
Combine [tex]y^{2}[/tex] and [tex]\frac{x^3*5}{4}[/tex]
[tex]\frac{y^2x^3*5}{4}[/tex]
f(x) =∛2x g(x)=2x+1 Find (f/g) (x) Include any restrictions on the domain
Answer: ∛2x / 2x+1
x cannot equal -1/2
Step-by-step explanation: f/g means we divide the f function by the g function
so that’s all we do!
then, remember, we can’t divide by 0. so 2x+1 can’t be 0. if we solve that out, we get that x can’t be -1/2, because that would make it 0. there’s our domain restriction!
PLEASE PLEASE HELP I NEED THE ANSWER SOON
9514 1404 393
Answer:
A, C
Step-by-step explanation:
The domain is the list of x-values in the table. Choice A correctly lists the domain values.
The range is the list of y-values in the table. Choice B incorrectly describes the domain.
For x = -1, the table tells you f(x) = 6, so f(-1) = 6.
For x = 5, the table tells you f(x) = 12, so f(5) = 12, not -2.
Choices A and C are correct.

Answer:
16/625
Step-by-step explanation:
Step one:
sample space
A bag contains
5 cherry,
8 orange,
2 grape,
7 bubblegum, and
3 apple lollipops.
sample size= 5+8+2+7+3= 25
Required:
The probability of choosing grape for your first lollipop
and orange for your second?
1. The probability of choosing the grapes lollipops
=2/25
2. the probability of choosing the orange lollipops----Note in the second choice the sample size will reduce because the first choice was done with out a replacement
=8/24
The total is
2/25*8/25= 16/625
