Set up a ratio:

12/5x-2 = 16/6x

Cross multiply:

12(6x) = 16(5x-2)

Use distributive property:

72x = 80x - 32

Subtract 80x from both sides:

-8x = - 32

Divide both sides by -8:

X = 4

I have 54 coins in my pocket; some of them are quarters and the rest are nickels. In total, the coins are worth $6.10. How many
ss7ja [257]

Answer:

17 quarters, 37 nickels

Step-by-step explanation:

We just have to set up a system of equations

quarters are x

and nickels are y

x+y=54

0.25x+0.05y=6.10

now we can get ready to substitute

x=54-y

substitute it in

0.25(54-y)+0.05y=6.10

simplify/evaluate

13.5-0.25y+0.05y=6.10

-0.2y=-7.4

y=37

plug it back in

x+37=54

x=17
