Find out X
Answer:
x = 6/9
Step-by-step explanation:
9x - 2(x+8) = 5x - 11(2-x)
9x - 2x - 16 = 5x -22 + 11x
collect the like terms
7x - 16 = 5x -22 + 11x
7x-5x = -22 +16 + 11x
2x = -6 + 11x
6 = 11x - 2x
6 = 9x
divide both sides by 9
6/9 = x

Answer:
cool
Step-by-step explanation:
We first write the fractions in their decimal forms and find out the ratio.
2 1/4 is equivalent to 2.25, and 1 1/3 is equivalent to 1.33
Ratio will be 2.25 / 1.33 = 1.69 or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1
Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds
Quantity of gravel sold will be 172 -108. 2 = 63 .8 pounds
