If x^3 = 729, x = 9.
Then, plug that into x^2 + x
9 ^ 2 + 9 = 81 + 9 = 90
Answer:
x=6/5 or 1.2
Step-by-step explanation:
I could not tell if your original problem was 2=-5x+8 or if it should have been 2x=-5x+8 so I solved both
2= -5x+8 (next subtract 8 from both sides)
-6= -5x (divide both sides by -5)
-6/-5=x (the negative cancel out next)
6/5 or 1.20 is x
If your original problem should say 2x=-5x+8
2x=-5x+8 (add 5x to both sides next)
7x=8 (divide by 7 on both sides)
x=8/7
Answer:
$83.04
Step-by-step explanation:
1. Add up all the prices (49.99, 13,99, 13.99) = 77.97
2. Tax is 6.5% (.065 in decimal form)
3. Multiply 77.97 * .065 = 5.06805
4. 5.06805 rounds to 5.07
5. Add the total purchase (77.97) to the tax (5.07) = 83.04
