800 because 80% of 800 is 640
Answer:
The stack will be 4.54 feet tall
Step-by-step explanation:
Firstly, we want to write the decimal expression for 2 3/11
That will be 2 + 0.2727
To 2 decimal place, that will be 2.27
Staking the two boxes means we are placing one on the other
So the height of the stack will be 2.27 + 2.27 = 4.54 feet
Substitute
6(8) - 19 + (2)
6(8) = 48
48 - 19
29 + 2 = 31
15. 1hour 7minutes and 5seconds
So to solve for y, subtract 108 from each side.
The equation becomes -y=126
Since you don't want y to be negative then divide each side by -1 this will flip all of the signs (positives become negative and vice versa) without changing the number.
So the equation is now y= -126
