<span>3t + 2 = 5(t – 2) – 2t + 8
Start by distributing...
3t + 2 = 5t - 10 - 2t + 8
Combine like terms....
3t + 2 = 3t - 2
Subtract 3t from both sides
2 = -2
Since 2 is NOT equal to -2 there is no solution for this equation</span>

Answer:

Step-by-step explanation:
We are given that
Sophomores=13
Juniors=12
Seniors=8
Male sophomores=5
Female sophomores=6
Male seniors=4
We have to find the probability of randomly selecting a junior or a senior.
Total persons=13+12+8=33
Let A=Seniors
B=Juniors
Probability,P(E)=
Using the formula of probability







Hence, the probability of selecting a junior or senior=
Answer: 35%
Step-by-step explanation:
Let the original price be "4x".
60% gain on 1/2 of them will be:
(1.60 × 2x) = 3.2x - 2x = 1.2x
20% gain on (1/4) of them will be:
(1.2 × x) = 1.2x - x= 0.2x
Total gain 1.2x + 0.2x = 1.4x
Total gain percent= Gain/Original price =1.4x/4x = 0.35 = 35%
