Answer:
3.8 miles
Step-by-step explanation:
Lillian wants her mileage total to be ...
12 +3x = 23.4 . . . . an equation that can be used to find x
4 + x = 7.8 . . . divide by 3
x = 3.8 . . . . . . subtract 4
Lillian would have to ride an average of 3.8 miles each day to reach her goal.
Answer:
220
Step-by-step explanation:
11 classes total 11 multiplied by 20=220
Answer:
slope is 1 and y-intercept is (0,-5)
Step-by-step explanation:
perimeter = 20 +20 +24 = 64 feet
area = 12^2 + x^2 = 20^2
144 + x^2 = 400
x^2 = 256
x = sqrt(256) = 16 feet
area = 1/2 x 16 x 24 = 192 square feet
cost = 192 x $2 = $384
