Answer:
a = -677.29
Step-by-step explanation:
a/8.9 + 99.7 = 23.6
Minus 99.7 from both sides
a/8.9 = -76.1
and multiply both sides by 8.9
a = -677.29
9. You shouldn't agree, because they are equal to one another.
10. 84 cents plus 61 should be $1.45 because 84 + 61 is 145 and 100 cents equals 1 dollar, and then you have 45 left over.
100 - .63 is .37 because the whole painting is equal to 1, or .1, or in this case I used it as 100. The drawing is up to you, but you can just draw a canvas and shade in a little bit more than half but not the full canvas. .37 of the canvas is left.
Answer:
Step-by-step explanation:
1. -3( x - 4) = 2x + 4 - x
-3x + 4 = x + 4
4 = 2x + 4
2x = 0
x = 0
2. 4 + 2 (x - 2) = 2 (x - 1) + 2
4 + 2x - 4 = 2x + 2 + 2
2x = 2x + 4
x = 4
3. 3(x - 4) = 2x - 7 + x
3x - 12 = 3x - 7
x = 5
4. 4x + 15 = 3(x + 5)
4x + 15 = 3x + 15
x = 0
5. 2(x - 3)
for the rest i'm confuse what it is suppose to be
