Answer:
Hence, there is 5 gallons of fuel Roselyn needed for her journey.
Step-by-step explanation:
Since we have given that
Speed at which Roselyn wants to drive her car = 60 miles per hour
Time taken by her car = 1.5 hours
As we know the formula for "Distance-Speed " :
Her car has fuel efficiency = 15 miles per gallon
Number of gallons of fuel is given by

Answer:
r = -23
Step-by-step explanation:
A slope of 1/2 means that for every y-value increase of 1, the x value will increase by 2.
Between -7 and 5, there was an increase of 12. So, the x value will increase by 24.
To find r, subtract 24 from 1
1 - 24
= -23
So, r = -23
Answer:
8
Step-by-step explanation:
x = nickles
y = dimes
0.05x + 0.10y = 1.70
x + y = 21
y = 21 - x
0.05x + 0.10 (21 - x) = 1.70
0.05x - 0.10x + 2.10 = 1.70
-0.05x + 2.10 = 1.70
-0.05x = -0.40
x = 8
The answer is 5. In a slope-intercept form equation, the slope is always the coefficient of x. The slope is 5.
