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.

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.

Step-by-step explanation:
The highest boiling point on the chart is 280 which belongs to Phosphouors, meaning that it has the highest boiling point. If you count it out, -183 you'd have to add 183 to get to 0, with 184 you would have to minus 184 to get to 0. So therefore oxygen's boiling point is closer to iodine.
Graham paid $87.45 for a pair of jeans. This amount included a tax of 40%. What was the cost of the jeans before tax?
Answers
The final price is the cost plus the tax.
Since we know the tax and a percent, we can write this as
T = C(1+r)
T = what Graham paid = $87.45
C = cost before tax
r = tax rate expressed as a decimal = .40
Plugging in what we know
87.45 = C (1+.4)
87.45 = C(1.4)
Divide both sides by 1.4
C = $62.46

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.
