Answer:b
Step-by-step explanation:
-2/3 / -15
Find the reciprocal of -15 and multiply:
-2/3 * -1/15
Multiply the numerators and denominators together:
2/45
4(2x + 10)=0
8x + 40 = 0
8x = -40
x = -5
2220 miles divided by 554mph would give you 4 hours
This is how the calculation is done
1/2 = 24/x
x = 48
