Answer:
Step-by-step explanation:
This only works if the room is a prism shaped, or cylinder.
Volume of a prism or cylinder is area of he base times height. So since we know the height and volume we can fand the area.
V = h*B
B = V/h
B = 400/25
B = 8
This is a very narrow room, anyway, the area of the base, which we want to carpet is 8 square meters. Can you figure out how much it will cost since each square meter will cost 5?
Let's solve for x.
-5x+y= -2
step 1: add -y to both sides.
-5x + y -y = -2 + -y
-5x = -y -2
step 2: divide both sides by -5
-5x/-5 = -y-2/-5
answer:
x= 1/5 y+ 2/5
Well what I would do is split the 40% into 20% so from 40% to 20% that is /2. So 32/2=16 so 20% of a number is 16, we know there is 5, 20% in 100% so multiply 16 and 5 which gives you 80. Now 25% of 80 is the same as 80*.25 or 80/4 which is 20
Your Answer 20
Answer:15
Step-by-step explanation:
5x=40 (replace x by-5)
(5*-5)+40
=-25+40
=15
