(7+1÷5)−(4+5÷8) = 2 23/40 B
Step-by-step explanation:
7 1/5 - 4 5/8
= 36/5 - 37/8
Taking LCM
= 288/40 - 185/40
= 103/40
= 2 23/40
set each factor equal to 0
4x-3 = 0
2x-1 = 0
solve for x.
4x-3=0
4x=3
x= 3/4
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
