Answer:
32
Step-by-step explanation:
let the number be n , then
n + 
n = 12 ( multiply through by 8 to clear the fractions )
2n + n = 96
3n = 96 ( divide both sides by 3 )
n = 32
The number is 32
Answer:
14.4 inches to the nearest tenth.
Step-by-step explanation:
The square has area x^2 where x is the length of each side so:
x^2 = 13
x = √13.
The perimeter is the distance all around the square and this is 4x so we have the answer 4 *√13
14.422 inches.

32 + 24 = 56 hours
- You need to keep what you multiply, (ex. 8), the same as you work through this problem.
- Such as this problem, sometime the best methods are to just guess and check. This means to think of a number that is reasonable and try it. For example, if you try 5 and you see it is too low, go higher. Keep doing this and you would have got to 8 eventually.
20% red, 30% orange, 5% yellow, 10% green, totaling 65%.
Leaving 35% blue = 0.35(120) = 42
5% are yellow : .05(120) = 6
42 - 6 = 36 <== difference
