Answer:
1, 2, 3, 4
Step-by-step explanation:
- 4 1/3·1 = 4 1/3 Good
- 7 1/3·2 2/5 = 22/3·12/5 = 110/15·36/15= 3960/225 = 17 3/5 Good
- 6 2/3·1/2 = (6 2/3)/2 = 3 1/3 Good
- 4 1/2·2 1/6 = 9/2·13/6 = 27/6·13/6 = 9 3/4 Good
- 5·3 1/4 = 20/4·13/4 = 16 1/4 Doesn't Work
Answer:
Shanice
Step-by-step explanation:
<u>Michael</u>
4 1/4 times 3 = 12 3/4
<u>Shanice</u>
2 3/4 times 5 = 13 3/4.
Now we have to find the difference so
13 3/4 - 12 3/4 = 1
Therefore Shanice runs more miles in a week!
Answer:
It’s 135
or 67.5
Step-by-step explanation:
X² + x - 12 / x² - x - 20 ÷ 3x² - 24x + 45 / 12x² - 48x - 60
x² + x - 12 / x² - x - 20 * 12x² - 48x - 60 / 3x² - 24x + 45
<u>(x² + x - 12)(12x² - 48x - 60)</u>
(x² - x - 20)(3x² - 24x + 45)
