To find x, we simply need to subtract the sum of the other two sides from 73.
35+11=46
73-46=27
So x = 27mm
132 = 1/2x + 2(x - 9)
132 = 1/2x + 2x - 18
132+ 18 = 2.5x
150 = 2.5x
150/2.5 = 60......price of adult ticket
a childs ticket is 9 less then adults......so 60 - 9 = 51 <== childs ticket
Answer:
First blank: non-viable solution because the costs aren't less than the revenue
Second blank: viable solution because the costs are less than the revenue
Step-by-step explanation:
First: Insert the x into the equation and work it out to see if it is less than the y.
(30,90) x=30 y=90
y=1.5(30)+45
y=45+45
y=90
Non-Viable
Second: Insert the x into the equation and work it out to see if it is less than the y.
(60,160) x=60 y=160
y=1.5(60)+45
y=90+45
y=135
Viable

a number increased by 14
x + 14
Answer:
As j decreases, the expression increases.
Step-by-step explanation:
As j decreases, the expression will increase. This is because once it becomes a lower number, it will subtract less from 150, and it will soon eventually add towards with 150, if j is negative.
Hope this helps!
