Could something me with this, it's easy.

C. 14 3/4

Step-by-step explanation:

I entered it into my graphing calculator.

Step-by-step explanation:

4 7/12 + 2 3/4 + 7 5/12

Convert 2 3/4 to a common denominator

2 3/4 · 3/3 = 2 9/12

Then add

4 7/12 + 2 9/12 + 7 5/12 = 14 3/4 (c)

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
