The rational number would be 16
Answer:
Step-by-step explanation:
8x² + 2(x²-1) = 8x² + 2*x² - 2*1
= 8x² + 2x² -2
= 10x² -2
Like terms: 8x² , 2x²
You would make a pie figure come up with the problem like say 4/5 you would have five pieces of pie and four are black so one white pie pieces and four black ones
Each oil change ( x ) takes 22 minutes which can be represented as 22x.
Each tire rotation ( y ) takes 18 minutes, can be represented as 18y
Now, we have only 5500 minutes available, therefore the sum of both things can not last more than this time.
The inequality represented is:
7/10 = 0.70. They are equal.
