Answer:
72 +13n = 163
7 nights
Step-by-step explanation:
At 13 pages per night, Mario will read 13n pages in n nights. That plus the pages already read will total 163:
equation: 13n +72 = 163
__
To solve this, we can subtract 72, then divide by the coefficient of n.
13n = 91 . . . . . . subtract 72 from both sides
n = 7 . . . . . . . . divide both sides by n
Mario read 7 nights.
Answer:
1 pair of jeans and 3 sweatshirts
Step-by-step explanation:
41-17=24
24/8=3
In total, they would need 4 pumps. If we divide 55 by 17, we get just more than 3. This little more would need an entire pump. So the answer 4 total, 3 added
Divide the number of guest that came by the number of guests invited: 104/125=.832 or 83%. 83% of the invited guests were there :)
x² + 3x - 10 = 0
x = -(3) ± √((3)² - 4(1)(-10))
2(1)
x = -3 ± √(9 + 40)
2
x = -3 ± √(49)
2
x = -3 ± 7
2
x = -3 + 7 U x = -3 - 7
2 2
x = 4 U x = -10
2 2
x = 2 U x = -5
Solution Set: {2, -5}
