x-3. eq 1
x+1 eq 2
4x-2 eq 3
Add equation 1 ,2 ,3
x -3 + x +1 +4x-2 =0
6x - 4 = 0
x = 4/6
x = 2/3

Answer:
Mr. Mosey needs 9/2 cups of cocoa to make a 32 serving cake.
Step-by-step explanation:
For an 8 serving cake Mr. Mosey needs 3/4 cups of cocoa plus 3/8 cups of cocoa because he wants it to taste better. Then, for an 8 serving cake he needs:
Cocoa (8 serving cake)=3/4+3/8= 9/8 cups
But, he needs to make a cake that serves 4 times as many people, then he need a 32 serving cake (8*4=32). What we do is to multiply the above formula times 4:
Cocoa (32 serving cake)= 4(3/4+3/8)= 36/8 cups= 9/2 cups
He needs 9/2 cups of cocoa to make a 32 serving cake.
Answer:
-3
Step-by-step explanation:
(x+3)(x-1) - x(x+2)
Foil the first term
First x^2
outer -x
inner 3x
last -3
Add them together
x^2 -x+3x-3 = x^2 +2x-3
x^2 +2x-3 - x(x+2)
Distribute the second term
x^2 +2x-3 -x^2 -2x
Combine like terms
-3
