It depends on the width of the building. Example: If the building is 10 feet wide (10 ft wide x 42 linear ft = 420 sq ft) or (420 sq ft divided by 10 ft wide = 42 linear ft.) the linear feet is 42. If the building is 20 feet wide (20 ft wide x 21 ft wide = 420 sq ft) or (420 sq ft divided by 20 ft wide = 21 linear ft.) the linear feet is 21.

1) 2x + 5y = 7

2) 3x + 6y = 3

I'm going to use the method of elimination to solve for x and y.

Multiply 1) by 3 and 2) by 2 to allow the x's to be eliminated.

1) 6x + 15y = 21

2) 6x + 12y = 6

Now subtract line 2 from line 1.

0x + 3y = 15

---- ----

3 3 divide both sides by 3 to get y by itself.

y =5.

Substitute into 1) to calculate x.

2x + 5(5) = 7

2x + 25 = 7

2x + 25 -25 = 7 - 25

2x = -18

---- ----- divide both sides by 2 to get x by itself

2 2

x = -9

Check by plugging in answer into the other equation, in this case 2)

3 (-9) + 6(5) = 3

-27 + 30 = 3

3 = 3

We did it correctly and checked to prove that we did it right.

Good luck.

Multiply 21 inches by 14 inches by 10 inches to get 2940 cubic inches. There are 12 inches in a foot, so there are 12^3=1728 cubic inches in a cubic foot. Divide 2940 cubic inches by 1728 cubic inches per cubic foot to get about 1.7 cubic feet.

Alternatively, first convert all measurements to feet. 21 inches is 1 3/4 feet, 14 inches is 1 1/6 feet, 10 inches is 5/6 feet. Multiply them together to get 245/144 cubic feet, which again is about 1.7 cubic feet.

It's always nice when doing a problem two different ways gives the same answer.

Start by using the distributive property to expand the term 5(I-31)=5*I-5*31=5*I-155.

Rewrite the equation as 5*I+5*I-155=55

Combine the terms with I, this yields 10*I-155=55

Add 155 to both sides of the equation 10*I-155+155=55+155

you now get 10*I=210

Divide both sides of the equation by 10

(10*I)/10=210/10

Cancel the 10's on the left and divide 210 by 10 to get 21

Thus I=21

Basically you use the priority order of operations BEDMAS backwards

X = 3 (

10x minus 3x equals 20 plus 1

10X minus 3X is 7X (right?)

20 plus 1 is 21 (right?)

therefore:

7X = 21

now divide both sides of the equals sign by 7

7X divided by 7 equals 21 divided by 7

7X / 7 = 21/7

X = 3 (

It would seem to me that the answer was found at a grade 3 or 4 level

If you divide 288 by 4 you get 97. Then the 1 is carried to the 2 leaving 12. 12 divided be 4 is 3 leaving a result of 397.

Second one....

217 divided by 5 is 43.4 or 43 with a remainder of 2.

Leaving 5 divided by 5 equaling 1.

Combining the 1 with the 43 with a remainder of 2 bringing you a total of 143 r2

This as mentioned would be at a grade 3 or 4 calculation with no understanding of how to properly divide.

I hope this helps and gives you the "A" you're looking for.

All the best.
