Visit $25 allergy shot $8
4a + 1v =57
-2a +1v= 9
I will multiply the second by -1 to cancel v variable (elimination method)
4a +1v =57
2a -1v = - 9
add both
6a. = 48
a= 8
4a= 32
32 + v = 57
v= 25
32+25 = 57
-16 +25=9
The exact quotient of 162 ÷ 19 is 8 with a remainder of 10.
To estimate the quotient of 162 divided by 19, you can use rounding or long division.
Rounding:

Answer:
41.2 feet of wallpaper
100.8 square feet of carpet
Step-by-step explanation:
The wallpaper is going to be around all the four walls of the bedroom and to know how many feet of wallpaper we know that the bedroom is:
12.6 feet long and 8 feet wide.
So two walls are 12.6 feet and two are 8 feet, so we have to add the total of feet the perimeter of the bedroom is:
12.6+12.6+8+8 = 41.2 feet of wallpaper.
With the carpet, we need to know the area of the room because it will be on the floor. The formula for the area of a rectangle is:
A=L*W
where:
A is area
L is length
W is wide
Now we will substitute the data we have in the formula:
A = 12.6 * 8
A = 100.8 square feet of carpet.
