By making a the subject of formula in the given equation, the value "a" is equal to 1/(56Q + 32GQ).
<h3>What is an equation?</h3>
An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
In this exercise, you're required to solve for a from the given mathematical expression (equation) by making it the subject of formula. This ultimately implies that, all the other variables would be defined in terms of a and they would all be on the same side of the "equal to" symbol.
Making a the subject of formula, we have:
-4G + 1/8Qa = 7
1/8Qa = 7 + 4G
Multiplying both sides by 8Q, we have:
8Q × 1/8Qa = (7 + 4G) × 8Q
1/a = 56Q + 32GQ
a = 1/(56Q + 32GQ).

Answer:
the dryer costs $450
step-by-step explanation:
w + d = 831
w = d-69 (they told us we will have to take $69 from the cost of the dryer to determine the cost of the washer)
(d-69) + d = 831
Let's combine like terms
2d - 69 = 831
add 69 to both sides to solve for d
2d = 900
divide both sides by 2 to solve for d
d = 450; the dryer costs $450
The answer should be C. By combining like terms you can find the answer. 1.75a+2.75a = 4.5a
2.25b + 1.75b = 4b
2.25c + 1.25c = 3.5c
