<span>It's 1/5(m-100). What you do is 1/5 and connect it with what is in the parenthesis and your answer will be -20 just like when you do 1/5m-20</span>
Answer:
x= -18
Step-by-step explanation:
We want to isolate x ( move everything to the other side of the equation)
-7 = -1 + x/3
-6 = x/3
x= 3*-6
x= -18
H(t) = 0 for t = 7 and for t = -2.
It is reasonable for the time to be positive, 7 seconds.
(The offered answers all appear to be negative, so none are reasonable.)
