Answer:
D. 62 square feet
Step-by-step explanation:
uz + wx + (v+z)(y-u-w)
6*3 + 4*6 + (7+3)(12-6-4)
18 + 24 + 20 = 62
Answer:
go to m a t h w a y . c o m but dont add the spaces and it will give you the answer just type it exactly how you did on here
Step-by-step explanation:
1/10x200
= 1/10x200/1
= 200/10
=20
the answer is 20
if u dont understand, 1/10 means a part of 200 that is divided by 10 which means the number x10 =200. So if u dont understand, you can check answer this way: n*10=200
200/10=n
n= 20
Use linear combination to solve this. It is much faster than substitution. I would start by multiplying the bottom equation by -1.
<span>4x-7y=3
-x+7y=15</span>
Then, add the two equations together. The result is:
3x=18.
You've eliminated one variable. Now you can solve for the other one.
Divide both sides by 3 to get
x=6
Plug this into one of the original equations, then solve for y
-(6)+7y=15
7y=21
y=3
Check your work by plugging these values into both equations to see if they remain true
