-8(9)= -72; -4(-6)= 24; -72+24= -48
How concerned are you with how to get the answer?
Because I know the answer is 5 miles per hour
22/5= 4.4 hours
27/5= 5.4 hours
Alright this is how you solve it
Distance over time equals speed
So 22/y=x and 27/y+1=x
Start by solving for time by having these two equations equal each other
22/y=27/y+1
Cross multiply to get
22(y+1)=27y
22y+22=27y
Isolate Y
5y=22
Y=4.4
Now solve for X which is the speed, you can plug in Y to either of the two equations
22/4.4=x
X=5 miles per hour
Answer:
556
Step-by-step explanation:
Because thats the answer
Radius / diameter as a length cannot be negative, that's why '-16' is wrong.
the answer is 7Г2÷2 (the first one)
