Sorry need points don't know the question
Answer:
= 45 miles per hour
Step-by-step explanation:
First, we want a unit rate where 1 is in the denominator.
So we divide,
180 miles/ 4 hours both ÷ by 4
= 45 miles/ 1 hour
= 45 miles/ hour
= 45 miles per hour
Yo sup??
x+y=4 -----1
x-y=6 ----2
adding equation 1 and 2 we get
2x=10
x=5
from equation 1 we get
5+y=4
y=-1
Since a definite value of x and y exists therefore the set of equations are consistent.
Hope this helps.
