monitta

Answer:

9 nickles

15 dimes

21 quarters

Step-by-step explanation:

Number of nickels = N

Number of dimes = D

Number of quarters = Q

The following system can be modeled based of the given information:

$0.05N+0.10D+0.25Q=7.20\\D=N+6\\Q=D+6$

Solving the system:

$D=N+6\\Q=N+6+6=N+12\\0.05N+0.10*(N+6)+0.25*(N+12)=7.20\\0.4N=7.20-0.6-3\\N=9\\D=9+6=15\\Q=15+6=21$

The collection consists of 9 nickels, 15 dimes and 21 quarters.

marishachu [46]

Answer:

x= 13

Step-by-step explanation:

−4/9(18x − 36) = −88

we need to solve the equation for x

$\frac{-4}{9}(18x - 36) = -88$

First we remove the fraction -4/9

Multiply by -9/4 on both sides

$\frac{-9}{4}*\frac{-4}{9}(18x - 36) = -88*\frac{-9}{4}$

18x -36 = 198

Now add 36 on both sides

18x = 234

Divide both sides by 18

x = 13
