Step-by-step explanation:
Vina has $4.70 in quarters, dimes and nickels in her purse. She has nine more dimes than quarters and four more nickels than quarters. How many of each coin are in her purse?
nickels
dimes
quarters
15x plus 7
This is because you just simplify the like terms
The answer has to be 16 because when you add them it goes up
10⁶= 1 million= 1,000,000
10⁷=10 million= 10,000,000
25 students got 2 chaperones
so 1 will get 2/25
and thus 8 will get 2/25×8 = 0.64 chaperone
but is it possible?? No chaperone can not be in decimal so at least 1 is required !!
