Answer:
1100 - 0.04x
Step-by-step explanation:
0.07x + 0.11(10,000 - x)
0.07x - 0.11x +1100
-0.04x + 1100
Cross multiply
5/8 and 8/10
5x8=40
8x8=64
40 does not equal 64 so not proportional
Answer:
$78.69
Step-by-step explanation:
63.04+58.27=121.31
200-121.31=78.69
<h3>The value of y is equal to 1.</h3><h3>The value of x is equal to 4.</h3>
Because both equations have a term that will cancel out if they're added together, we're going to add both equations together.
-5x + 5x = 0
13y + 4y = 17y
-7 + 24 = 17
17y = 17
Divide both sides by 17.
y = 1
Now that we have a constant value of y, we can solve for x.
-5x + 13(1) = -7
-5x + 13 = -7
Subtract 13 from both sides.
-5x = -20
Divide both sides by -5.
x = 4
