Answer:
Jayanta needs 2 labor union groups and 8 church groups.
Step-by-step explanation:
Let c denotes churches
.
Let l denotes labor unions.
We know that Jayanta can only spend 20 hours letter writing and 14 hour of follow-up.
So, equations becomes:
And total money raised can be shown by = 
We have to maximize keeping in mind that 
and 
We will solve the two equations: and
We get l = 2 and c = 8
And total money raised is 
= 
dollars.
Hence, Jayanta needs 2 labor union groups and 8 church groups.

Answer:
x = 6
Step-by-step explanation:
Ratio between the top and bottom of the adult's chair is 7/14, or 1/2
So that means, x is equal to 12 x 1/2, or 6.
To solve this, you can set up an equation. Make the length of the shortest side x, so the 2 sides double the length will equal 2x. Since they all equal the perimeter of 36, do x + 2x + 2x =36. These values all represent the sides(2 longer, one short). Combine like terms to get 5x=36 then divide by 5 to find the value of x. x=7.2in meaning the shorter side is 7.2 inches while the longer sides are both 14.4 inches each since they are double in size.
