Answer:
9 tickets
Step-by-step explanation:
Let x = the number of tickets
let y = the total she spends
So y = 5 + 8 + 0.75x
If the max she can spend is 20, set y = 20 and solve for x:
5 + 8 + 0.75x = 20
13 + 0.75x = 20
0.75x = 20 - 13
0.75x = 7
x = 7 ÷ 0.75 = 9.333333333
Therefore, the max number of tickets that can be bough is 9
Answer:
61.8 square centimeters
Step-by-step explanation:
Answer: x = y + −3/2
Step-by-step explanation:
Let's solve for x.
−3+5y=2x+3y
Step 1: Flip the equation.
2x+3y=5y−3
Step 2: Add -3y to both sides.
2x+3y+−3y=5y−3+−3y
2x=2y−3
Step 3: Divide both sides by 2.
2x/2 = 2y - 3/2
ANSWER: x = y + -3/2
Answer: A.
