Answer:
16 weeks old
Step-by-step explanation:
Let x represent age of the flower in weeks.
x/4 + 2 = 8
x = 24 weeks
The flower would be 16 weeks old to be 8 feet tall.
The number of hours since the bakery opened, plus the number of remaining boxes is equal to 42.
x + y = 42
So the number of boxes remaining is equal to y, and
y = 42 - x, the number of hours the bakery was open.
So at the start of the day, the bakery was open for 0 hours, and y, the number of boxes "remaining" at the start of the day, will be equal to 42 - 0 = 42.

Answer:
Therefore the third container contains = 43.23 % acid.
Step-by-step explanation:
Given that, One container is filled with the mixture that 25% acid. 55% acid is contain by second container.
Let the volume of first container be x cubic unit.
Since the volume of second container is 55% larger than the first.
Then the volume of the second container is

Answer:
C
Step-by-step explanation:
Given
(3x² + 5x - 8) + (5x² - 13x - 5) ← remove the parenthesis
= 3x² + 5x - 8 + 5x² - 13x - 5 ← collect like terms
= 8x² - 8x - 13 → C
