Answer:
8 is subtracted from x
The inverse operation is addition
Add 8 to both sides
X=-2 so I think that it is: 10 is added to x
The inverse operation is subtraction
Subtract 10 from both sides
4 is multiplied by x
The inverse operation is division
Divide 4 from both sides
X is divided by 2
The inverse operation is multiplication
Multiply each side by 2
Hope it helps!
Answer:
100
Step-by-step explanation:
Hello! to calculate the number of tiles needed for the floor you need two things
1. number of tiles that fit across the width, this is achieved by dividing the total width by the width of each tile
Width=20ft=240in

2.number of tiles that fit in the logitude, this is achieved by dividing the total length by the length of each tile.
leght=30ft=360in

Finally, you multiply the number of tiles that fit in width by the number of tiles that fit in length.
N=10X10=100
Answer: 33.13 in
Step-by-step explanation:
First, let's start with the perimeter of the semicircles.
Since there are two, it is easier to do because the perimeter of the two halves will add to one full circle; so we can just calculate without having to halve anything.
The formula for the perimeter (aka circumference) of a circle is 2πr
Plug the radius into the equation to get 2π4, or 8π
8π ≈ 25.13
The perimeter of the rectangle is 6(4) = 24.
We now have to subtract the diameters of the circles, as they are not on the outside of the figure and won't be counted in the total perimeter. From the 24, we subtract the two diameters, or 16 in.
24 - 16 = 8
The total perimeter then comes out to be 25.13 + 8, or 33.13 in
