3 miles in 1 hour
Answer:
D: x = -18
Step-by-step explanation:
A good way to solve this it to input all options until you find the one that fits for both options.
Option A :
15 + 6 / 15 - 3 = 21 / 12 or 7/4
So this one doesn't work.
Option B :
10 + 6 / 10 - 3 = 16 / 7
So this one also doesn't work.
Option C:
3 + 6 / 3 - 3 = 9 / 0 which is 0 by the laws of dividing by zero.
This one also doesn't work leaving only one option.
Option D:
-18 + 6 / -18 - 3 = -12 / -21 or 4 / 7
And by solving we can find out we did our work correctly and get our answer.
Answer:
Set each factor equal to 0
4x-3 = 0
2x-1 = 0
Solve for x.
4x-3=0
4x=3
x= 3/4
Solve for x.
2x-1= 0
2x= 1
x= 1/2
Eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
