Answer:
x=11
Step-by-step explanation:
Add 7 to both sides
-3x+5x=22
combine like terms(-3x and 5x)
2x=22
divide by 2
x=11
Answer:
.76 x 10 or 7.6 x 10^0
Step-by-step explanation:
divide coefficients and subtract exponents
5.4 / 7.1 = .76
10^-7 / 10^-8 = 10
Answer:
Step-by-step explanation:
you need to simplify 8/20
8/20 can be put into the greatest common factor which is 4
then divide both sides by 4 this equals to 2/5
So yes they are
10x + 9
because the -6x and positive 6x cancel out and all you have left is 2+2+5 and 10x
