Step-by-step explanation:
5=(6y+9)
5-9=6y
-4=6y
-4/6=6y/6
y=-4/6
23 inches
x = Mindy's height
2x - 20 = 66
- 20 -20
2x = 46
/2 /2
x = 23
Answer:
Step-by-step explanation:
let price of one pretzel=x
price of one soda=y
3x+4y=11.25 ...(1)
5x+2y=8.25 ...(2)
multiply by 2
10x+4y=16.50 ...(3)
(3)-(1) gives
7x=5.25
x=0.75
from (1)
3(0.75)+4y=11.25
2.25+4y=11.25
4y=11.25-2.25
4y=9
y=9/4=2.25
cost of one pretzel=$0.75
cost of one soda=$2.25
