You get 2m+m-3n which simplifies to 3m-3n
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.
5.3-5=0.3
5.6-5.3=0.3
5.9-5.6=0.3
Common difference: 0.3
Step3 is wrong
7(3)+8-24 instead
