Answer:
The answer is actually x+y= 4
Step-by-step explanation:
I took the test
8.01
48*4=192mph
Answer is 192mph
310.39
total of ages now is 67 + 4 + 4 = 75
S=shelly
M= Michelle
Michelle is 3 yrs younger than Shelly so use S-3
S +M = 75
replace M with S-3 to get:
S +S-3=75
2S=78
s=39
So shelly is 39
Michelle is 3 years younger = 39-3 = 36
596 divided by 3=198
