Answer:
Choices C and D
Step-by-step explanation:
The most simplest way is just to solve each one and see which two have the same answer as the first expression.
But you could also see that both of the 
are going to cancel each other out so you are left with 
which is also choice C.
For choice D I distributed the negative one to the insides of the parenthesis that left me with 
which is the same expression as the first one.
It's kind of not C.
Solve this proportion for 'x':
3/50 = x/2400
Hint: Cross-multiply the proportion, then do what you need to do.
Answer:
The answer is 25
Step-by-step explanation:
Answer:16 quarters and 3 dimes
Step-by-step explanation:
430/25 (Quarters) = 17
25x16
(Because you can’t have 17 since 25x17=425 leaving no room for dimes.)
=400
Now 430-400=30
30 more cent is needed,
30/10(Dime value)
Is 3, so the answer is the man has 16 quarters and 3 dimes
