an architect created plans for a house using a scale factor of 1:16 . In the plans, the floor of the house has an area of 7 squa
Yuki888 [10]
To figure this out you would need to create a rectangle with dimensions that give you an area of 7 ft.². The easiest example would be a rectangle that is one by seven. If the scale is 1:16, that means for every foot it is actually representing 16 feet. The actual length and width would be found by multiplying 1×16 and 7×16. The true dimensions then would be 16 x 112. Multiply this together to get a total area of 1792 ft.².

Solve the equation. –x 8 3x = x – 6 x = –18 x = –14 x = 2 x = 4
LenKa [72]

The value of the variable x in the equation –x + 8 + 3x = x – 6 is - 14.

<h3>How to find variable in an equation?</h3>

The variables of an equation can be found as follows:

–x + 8 + 3x = x – 6

The variable in the equation is x.

Therefore,

–x + 8 + 3x = x – 6

combine like terms on the left side

-x + 3x + 8 = x - 6

2x + 8 = x - 6

subtract x form both sides of the equation

2x - x + 8 = - 6

x + 8 = -6

subtract 8 from both sides

x = -6 - 8

x = - 14

60 total fourth graders and 43 are girls. To find the number of boys, subtract.

60 - 43 = 17 boys

If 5 girls were absent, subtract.

43 - 5 = 38 girls present

If 4 boys were absent, subtract.

17 - 4 = 13 boys present

Therefore, there were 13 boys present.

Best of Luck!
