Hello!
We drove a total of 504 miles in 9 hours. How I solved this equation is by dividing 504 by 9. 504 / 9 = 56, as the answer. You could also solve this just by adding how many times 9 can go into 504, but that will be longer for the same result.
Enjoy.
Brainliest please?
Let x be the amount of nickels and y be the amount of quarters in a jar. Totally there are 87 coins, then x+y=87.
Since nickel is 5 cent coin and quarter is 25 cent coin, then 5x+25y=1255 ($12.55=1255 cents). Solve this system:x=87-y and 5(87-y)+25y=1255.
435-5y+25y=1255,
25y-5y=1255-435,
20y=820,
y=820÷20,
y=41,
x=87-41=46.
Answer: 46 nickels and 41 quarters.
I know the answer but first I need you to answer my math question
