Answer:
A = 78.5
C = 31.4
Step-by-step explanation:
Circumference = 2πr
r = 5
C = 2(3.14)(5)
Circumference = 31.4
Area = 
r = 5
A = 
Answer:
B. 7
Step-by-step explanation:
The original box must be 1 by 1 by 1.
So then the new box would be 2 by 2 by 2.

Answer: 
proportion of candies are green.
Solution:
In bag A, 
candies are yellow.
this proportion shows ratio of favorable over total candies.
Here numerator number is 2.
So, Total number of yellow candies should be 2x
Total number of candies in Bag A would be 3x
Number of green candies in bag A = 3x-2x = x
Now we find the portion of green candies in bag A
portion of candies are green in bag A
Answer:
Increases
Step by Step Explanation:
More time on your homework means more time to cheat/figure the answer out.
It depends on what variable you are tying to solve for first. Say you are trying to solve for x first and then y on the first problem you wrote.
In substitution you solve one of the equations for example with
6x+2y=-10
2x+2y=-10
you solve 2x+2y=-10 for x
2x+2y=-10
-2y = -2y (what you do to one side of the = you do to the other)
2x=-10-2y (to get the variable by its self you divide the # and the variable)
/2=/2 (-10/2=-5 and -2y/2= -y or -1y, they are the same either way)
x=-5-y
now you put that in your original equation that you didn't solve for:
6(-5-y)+2y=-10 solve for that
-30-6y+2y=-10 combine like terms
-30-4y=-10 get the y alone and to do this you first get the -30 away from it
+30=+30
-4y=20 divide the -4 from each side
/-4=/-4 (20/-4=-5)
y=-5
now the equation you previously solved for x can be solved for y.
x=-5-y
x=-5-(-5) a minus parenthesis negative -(- gives you a positive
-5+5=0
x=0
and now we have solved the problem. x=0 and y=-5
