Answer:
√a^3−7-4

Joe : x
jim : y
x+y=16
y=1.50+x
x + 1.50 + x = 16
2x = 14.5
x = 7.25
7.25 + y = 16
y= 8.75
Joe : $7.25
Jim : $8.75
Answer:
200+40+3+0.7+0.09
Step-by-step explanation:
4x - 13 = 2x + 9
Add 13 to each side
4x = 2x + 22
Subtract 2x from both sides
2x = 22
Divide both sides by 2
x = 11
