Answer:
She has 11 dimes and 17 nickels
Step-by-step explanation:
dimes --- d
nickels -- n
Equation with number of coins: ![ n+d = 28 n = 28-d](https://tex.z-dn.net/?f=%0An%2Bd%20%3D%2028%0An%20%3D%2028-d)
![10d + 5n = 195 ](https://tex.z-dn.net/?f=10d%20%2B%205n%20%3D%20195%0A)
Divide by 5
![2d + n = 39](https://tex.z-dn.net/?f=2d%20%2B%20n%20%3D%2039)
sub in the other equation:
![2d + 28-d = 39 d = 11 n = 28-11 = 17 ](https://tex.z-dn.net/?f=2d%20%2B%2028-d%20%3D%2039%0Ad%20%3D%2011%0An%20%3D%2028-11%20%3D%2017%0A)
She has 11 dimes and 17 nickels
check:
total = 11 + 17 = 28 , check!
value: 10(11) = 5(17) = 195 , check!
M=#miles
so 130= .5m+30
subtract 30 from each side
100$= .5m than divide .5 to isolate m
m= 200
