Answer:
13-13x
Step-by-step explanation:
3*2=6
(6-5x+6) + (9-8x-8)
Combine Like Terms
(12-5x) + (1-8x)
Put x on one side and numbers on the other.
(12+1) + (-5x+ (-8x))
13-13x
If you multiply 13.99x0.04=.5596
then you added
13.99+.5596=14.5496
And this is your answer
Answer:
2/9
Step-by-step explanation:
First, you want to make the 1 and 1/8 an improper fraction. now it should look like 1/4 divided by 9/8. There's this method I learned called "Keep, Change, Flip". Basically, you want to keep the 1/4 the way it is, change the division symbol to a multiplication symbol, and flip the 9/8 so it is now 8/9. The equation now looks like 1/4 x 8/9. The answer should be 8/36, which also equals 2/9. If you have any questions, I'll try my best to answer them. Sorry if this is too long.
