4,734 is the answer because I used my calculator XD
Answer:
Step 3
Step-by-step explanation:
Step 3 should be:
−6m + 6m = −48 − 12n + 4n + 4
Answer:
x=8.8
Step-by-step explanation:
Cross multiply
4/5=x/11
5*x=4*11
5x=44
Divide by 5 on both sides
x=8.8
Or, multiply both sides of the equation by 11
4/5=x/11
11*4/5=x/11*11
8.8=x
Hope this helps! :)
You will need 3 cans of paint to cover the two walls
<h3>
How many cans of paint will you need?</h3>
We know that 1 can will cover 200 square feet of wall.
And here we have 2 walls, let's find the total area of these walls.
wall 1 is 20ft by 8ft, then its area is:
A = 20ft*8ft = 160ft^2
wall 2 is 40t by 8 ft, then its area is:
A' = 40ft*8ft = 320ft^2
The total area is:
160ft^2 + 320ft^2 = 480ft^2
The number of cans of paint needed is given by the quotient between the total area and the area that each can cover.
N = 480ft^2/200ft^2 = 2.4
But we can't have a 0.4 of a can, so we should round to the next whole number, which is 3.
