The commutative property of addition is just switching the numbers around really! so yr answer would be 9+8=8+9
3 1 10
------ + --------------- = ----------
3x x +4 7x
1 1 10
------ + ------------ = ----------
x x +4 7x
x + 4 + x 10
------------------ = ----------
x(x +4) 7x
2x + 4 10
------------------ = ----------
x(x +4) 7x
7x(2x + 4) = 10x(x+4)
14x^2 + 28x = 10x^2 + 40x
4x^2 - 12x = 0
4x(x - 3) = 0
4x = 0
x = 0
x - 3 = 0
x = 3
answer x = 0 and x = 3
Answer:
Lucy reads 10 fewer pages that Carey
Step-by-step explanation:
The first sentence reads as Carey having more, so Lucy has fewer,
