Answer:
$2.50
Step-by-step explanation:
Jake's total expenditure is ...
total = admission + c × (number of tickets)
36 = 13.50 + 9c . . . an equation to solve
4 = 1.50 +c . . . . . . . divide by 9
2.50 = c . . . . the cost of one ticket
Each ticket cost Jake $2.50.
2x+15 = 3x-25
2x-3x = -25 -15
-x = -40
x = 40
So you just plug in the X value of the number that d represents for example if I plug in 2 for d
7(2)^2+10=38
-18 because a negative number times positive is negative.
