What does the variable r represent in the equation 10r+4=8?

1 answer:

8 0

R =

I think “represent” is asking you to solve to a number.

10r + 4 = 8
Subtract 4 from both sides of the equation:
10r = 4
Divide both sides by 10:
r = 0.4

Check the math:

10(0.4) + 4 =
4 + 4 = 8

Evaluate the following expression when x = -5 and y = 25.

kykrilka [37]

Answer:

The correct answer is A. 3,120.

Step-by-step explanation:

Let's solve the expression for x = -5 and y = 25, this way:

(5|x| - y³)/x

Replacing x and y, we have:

(5 * 5 - 25³)/-5 (Absolute value of -5 is 5 in the numerator but we keep it without changes in the denominator)

(25 - 15,625)/-5

-15,600/-5

3,120

The correct answer is A. 3,120.
