x=7 because if you replace x with 7 then 4 times 7 is 28 and 28 minus 6 is 22
The answer should be
f=1/5 x^2 + -2/5x
Answer:
2 x 4.99 = 9.98
3/4 x 4.99 = 3.7425 round it to 3.74
9.98 + 3.74 = 13.73
Answer: $13.73
Step-by-step explanation:
Answer:
140 minutes
Step-by-step explanation:
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
20/4 = 5
5x28 = 140
