The answer is 9. if you wanna do it the long way buit a calculator is easier
Answer:
The answer is 12 because 2x is just 8 and 2y is just 6 so add that and get 14 then subtract 2.
Step-by-step explanation:
Answer:
w=-y+1/2x
Step-by-step explanation:
Its literal equations, so just solve like any other variable equation. Set your w value to the equal, and isolate the said variable
Answer:
Step-by-step explanation:
y = x
The constant of proportionality is 1 although you cannot see it. It is understood to be there.
y = (-8/5) x
This is a nasty piece of work and it depends on your grade level. If you are below grade 8, you are not encouraged to think of a constant of proportionality as less than 0.
In general the opinion is split. Some people say yes others no. If you twist my arm and put a gun to my head, my answer would be that it's fine, but it is a matter of what you have been told. I would read your notes.
To find the area of all of the figures, all you need to do is base x height or the length x width.
Your answers for 1-6 are all correct.
For 7-9, remember that the area is the length times the width.
7) length x width, 42 x 30=1260
8) 17 x 22= 374
9) Since the length and width are the same in a square just multiply the side by itself. 2.7 x 2.7= 7.29
Hope this helps.
