800 is 100% so 20 is 40% of 800.
Answer:
<h3>HLO,,,WE HAVE TO SIMPLIFY OR WE HAVE TO FIND VALUES</h3>
standard from Ax +By = C
y = 4x+10
subtract 4x from each side
-4x+y = 10
or 4x - y = -10
Answer:
This question requires us to change the subject of a formula. This can be achieved by following the order of operations in reverse. First, isolate the terms with our variable of interest, x:
ax - bx = z - y
Then, we take x out as it is being multiplied to both a and b:
x(a - b) = z - y
Dividing (a - b) on both sides, we get:
x = (z - y) / (a - b)
Thus, the answer is x= z-y/a-b
