Answer:
I would assume it's all but the second one (earned $60 over the summer=false)
1a+-1+a I believe that would be the answer
b
Step-by-step explanation:
because it will be right always because if you mutiply all of them then you get your right answer
we are given
-3 x 2(4-18) + 8 =
Firstly , we will solve inside parenthesis
now, we can multiply

Answer & Step-by-step explanation:
Using the information given in the question we can form the following 3 equations (in the order of the first 3 sentences)
w = 2h (twice the price)
t = h - 4 ($4 less)
3w + 2h + 5t = 136 (total purchasing and cost)
We can solve all 3 equations for h first, by substituting the first two equations, into the third equations w and t
3(2h) + 2h + 5(h-4) = 136
Simplify
6h + 2h + 5h - 20 = 136
13h = 136 + 20
13h = 156
h = 156/13
h = $12
Using this information, we can solve for w and t
w = 2h
w = 2(12)
w = $24
And finally
t = h - 4
t = 12 - 4
t = $8
