18 gallons of milk had passed the expiration date.
Explanation step by step
Multiply 120x 15%
Turn 15% into a decimal which is 0.15 so now it’s 120x0.15 which equals to 18.
X% of 150 = 108
x/100 * 150 = 108
1.5x = 108
x =108 / 1.5
x = 72
Therefore 72% of 150 is 108
Hope this helps.
I am thinking on this question hold up
Answer:
2 x 7
Step-by-step explanation:
a * b = 14
2a + 2b = 18
(a * b)/b = 14/b Dividing both sides by b
a = 14/b
Substitute a in the perimeter equation
2(14/b) + 2b = 18
28/b + 2b = 18
2b - 18 + 28/b = 0
Multiply both sides by b
2b^2 - 18b + 28 = 0
Divide both sides by two
b^2 - 9b + 14 = 0
The Factors of 14 include -2 and -7 which add up to -9
(b - 2) * (b - 7) = 0
This has two answers because b can be either the side that is 2 long or 7 long, so there's no need to go back and solve for a.
2 x 7
