First, we add the numbers. This gives us 715.
Then, we divide it by the amount of numbers. This gives us. 715 divided by 11.

This simplifies to 65.

Three-fourths was subtracted from a number, and then 5/4 was added to the result. The sum was -7.

Rasek [7]

Hi there!

Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :

(x - $\frac{3}{4}$ ) + $\frac{5}{4}$ = -7

subtract $\frac{5}{4}$ on each side of the equation

x - $\frac{3}{4}$ = -8.25

add $\frac{3}{4}$ on each side of the equation

x = -7.5

-7.5 - 3/4 = -8.25

-8.25 + 5/4 = -7

So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.

There you go! I really hope this helped, if there's anything just let me know! :)

Divide 72 ft in the ratio 9:4:5

Anton [14]

9:4:5.....added together = 18

9/18 (72) = 648/18 = 36
4/18 (72) = 288/18 = 16
5/18 (72) = 360/18 = 20

so we have 36:16:20
