Solve for a. m=a/9-H

Varvara68 [4.7K]

Answer:

9(m+H) = a

Step-by-step explanation:

m=a/9-H

The first step is to add H to each side.

m+H = a/9 -H+H

m+H = a/9

Now multiply both side by 9

9(m+H) = a/9*9

9(m+H) = a

6x+2y= 6x+2y= \,\,16 16 2x-2y= 2x−2y= \,\,32 32

Ivanshal [37]

Answer:

x = 6, y = -8

Step-by-step explanation:

First we take the equations side by side and put them like this:

6x + 2y = 16

+ 2x - 2y = 32

8x = 48

Then solve for x.

x = 6

Then insert x back into either equation

2(5) - 2y = 32

10 - 2y = 32

solve for y,

y = -10

Answer:

296 cubic feet

Step-by-step explanation:

First and foremost, you have to have everything in either feet or inches. Right now they are in both. Since the answer is asked for in feet, let's convert everything to feet. The width is already in feet, so that's good.

However, even though the length is 49 feet, we still have to convert the 4 inches part of that to feet. Using the fact that there are 12 inches in a foot:

$4in.*\frac{1ft}{12in.}=\frac{1}{3}ft$ so we have
