6. Solve for g: 7g + 8/3 + 6g + 12/9

Answer 1

Problem 1:

= 0.3(117)

= 35.1 answer

Problem 2:

= 100%(22/126)

= 1,100/63% or 17.46 1/550% answer

Problem 3:

= (42.9 in[3.3 in])/32.5 in

= 141.57 in/32.5 in

= 4.356 inches answer

Problem 4:

6x - 2 + 2x = - 2 + 4x + 8

8x - 2 = 4x + 6

4x = 8

x = 2 answer

Problem 5:

= (5q^4y^4)/(- q^4y^6)

= ([5q^4y^4]/[q^4y^4])/(- q^4y^6/q^4y^4)

= 5/ - y^2

= - 5/y^2 answer

Problem 6:

= 7g + 8/3 + 6g + 12/9

= 13g + 8/3 + 4/3

= 13g + 12/3

= 13g + 4 answer
