The answer is 30 ! Sub 3 and that's what you're answer should be
Answer:
d. 21
Explanation:
Step 1 - Subtract 13 from both sides
x + 13 = 34
x + 13 - 13 = 34 - 13
x = 21
It should take 45 minutes. 18/12=1.5
30 times 1.5 is 45
The answer to the question is 10
<span>Simplifying
-5(s + -30) = -10
Reorder the terms:
-5(-30 + s) = -10
(-30 * -5 + s * -5) = -10
(150 + -5s) = -10
Solving
150 + -5s = -10
Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-150' to each side of the equation.
150 + -150 + -5s = -10 + -150
Combine like terms: 150 + -150 = 0
0 + -5s = -10 + -150
-5s = -10 + -150
Combine like terms: -10 + -150 = -160
-5s = -160
Divide each side by '-5'.
s = 32
Simplifying
s = 32</span>
