Answer:
Step-by-step explanation:
U multiply it as u would multiply a two digit and a one digit number step by step only then u have to multiply the second number like u did to the other number and u add a zero then add them and u get ur answer
Write that as an equation and solve. (In math, "of" often means "times".)
8% × what = 2.8
0.08 × what = 2.8
what = 2.8/0.08
what = 35
8% of 35 is 2.8.
<span>t/(t-8)=(t+8)/30
(t+8)(t-8) = 30t
t^2 - 8^2 = 30t
</span>t^2 - 30t - 64 = 0
<span>(t-32)(t+2) = 0
so t = 32 and t = -2
answer: 2 solutions </span>t = 32 and t = -2<span>
