Answer:
97.5 miles
Step-by-step explanation:
d = 65t
where d is the distance in miles and t is the time in hours
Therefore, to calculate how many miles the car travels in 1.5 hours, substitute t = 1.5 into the equation:
d = 65 x 1.5 = 97.5 miles
Answer:
64
Step-by-step explanation:
1st step: 36/9 = 4
54 - 4 + 14 (since all operations are addition and subtraction, just work left to right)
50 + 14 = 64
F(-2)=1 the value for y when x=-2 is 1
