You worked 6 3/4 hours on monday 7 1/4 on tuesday 8 1/4 on wednesday 7 1/4 on thursday and 7 3/4 on friday how many hours did you work for this week

37 1/4 (answer)

Step-by-step explanation:

One way of approaching this problem would be to rewrite each proper fraction as a decimal fraction:

6.75

+7.25

+8.25

+7.25

+7.75

This comes out to 14 + 15.5 + 7.75, or

                               29.5 + 7.75, or

                               36.0 + 1.25, or 37.25.  This is the same as 37 1/4 (answer)

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
