15 – 5(4c – 7) = 50 pls solve C
Answers
Answer:
c = 0
Step-by-step explanation:
15 – 5(4c – 7) = 50
Expand.
15 - 20c + 35 = 50
Isolate 20c.
-20c = 50-15-35
Evaluate.
-20c = 0
Remove the negative sign.
-20c × (-1) = 0 × (-1)
Two negatives make a positive. Anything multiplied by 0 becomes 0.
20c = 0
Find c.
c = 0 ÷ 20
Evaluate.
c = 0
c = 7/4 is the solution to the equation 15 - 5(4c - 7)
Let's solve the equation step by step:
15 - 5(4c - 7) = 50
First, distribute the -5 to the terms inside the parentheses:
15 - 20c + 35 = 50
Combine like terms:
50 - 20c + 35 = 50
Combine the constant terms:
-20c + 85 = 50
Next, isolate the term with c by subtracting 85 from both sides of the equation:
-20c = 50 - 85
Simplify:
-20c = -35
Finally, divide both sides by -20 to solve for c:
c = (-35) / (-20)
Simplifying the division:
c = 7/4
Therefore, the solution to the equation 15 - 5(4c - 7) = 50 is c = 7/4.

In a music competition, a participant has to score a total of 40 points in the first four rounds combined to move on to the 5th and final round. Glen scored 4 points in the first round. He then went on to score additional points in the second, third and forth rounds. In each round he scored the identical points. Which inequality shows the number of points Glen scored.
Answers
Answer:
x ≥ 12
Step-by-step explanation:
Given that :
Total points required = 40
1st round point = 4
2nd, 3rd and 4th round points are identical
Let the point number of points = x
2nd + 3rd + 4th = 3
1st round + 3(x) ≥ 40
4 + 3x ≥ 40
3x ≥ 40 - 4
3x ≥ 36

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.

The vertices of are F(2,1), G(4,1), and H(4,-1). The vertices of the image of the triangle after a dilation centered at (0,0) are F'(4,2), G'(8,2), and H'(8,-2). What is the scale factor of the dilation?
Answers
Answer:
The scale factor of the dilation is 2
Step-by-step explanation:
The given vertices the ΔFGH are;
F(2, 1), G(4, 1), and H(4, -1)
The lengths of the sides of the triangle ΔFGH are;
The length of segment FG = √((4 - 2)² + (1 - 1)²) = 2
The length of segment FH = √((4 - 2)² + ((-1) - 1)²) = 2·√2
The length of segment GH = √((4 - 4)² + ((-1) - 1)²) = 2
After a dilation with the center of dilation = (0, 0), to give the ΔF'G'H', we have;
The given vertices the ΔF'G'H' are F'(4, 2), G'(8, 2), H'(8, -2)
The length of segment F'G' = √((8 - 4)² + (2 - 2)²) = 4
The length of segment F'H' = √((8 - 4)² + ((-2) - 2)²) = 4·√2
The length of segment G'H' = √((8 - 8)² + ((-2) - 2)²) = 4
The length of the sides of ΔFGH = 1/2 × The length of the sides of ΔF'G'H' or the length of the sides of ΔF'G'H' = 2 × The length of the sides of ΔFGH
Therefore, the scale factor of the dilation is 2.
