Answer:
A) 6x + 5y = 82
B) 2x + 5y = 54 We'll multiply equation B) by -1
B) -2x -5y = -54 Then we'll add this to A)
A) 6x + 5y = 82
4x = 28
x = 7
y = 8

Step-by-step explanation:
the shape is made up of 2 circles and one box add the 3 areas up
circle area = 
3.14*
= 50.24
50.24*2 =100.48
box, box, pit now :P ooh I was thinking formula one racing, ( i've been watching that lately) anyway
box = 8*8 = 64
total = 164.48 is that an option? hmm, yes the bottom two choices.. now the perimeter . the perimeter is made up of the 2 circles
the circumference of a circle is 2r
2**r
2**4 =25.1327 that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26
sooo
the 3rd choice looks good :)

Step-by-step explanation:
So, the question is asking for the difference between -8 and 2.
-----------------------------------------------------------------------------------------------------------------
Explanation 1:
2 - (-8) = ?
2 + 8 = ?
10 = ?
-----------------------------------------------------------------------------------------------------------------
Explanation 2:
|2| - 0 = 2
|-8| - 0 = 8
2 + 8 = 10
Answer:
No
Step-by-step explanation:
1. 5 cups of cornmeal=2 cups of water. Using 115 cups of cormeal would mean you need 287.5 cups of water, not 3.
3 is too little
2: If you use 5 cups of water for every 3 cups of cornmeal, for 3 cups of cornmeal you'd need like 6.5 cups of water, not that high of a number.
