If you would like to know the equation for the above expression, you can calculate this using the following steps:

x ... the number

x * 1/3 inches = 5/6 inches

x * 1/3 = 5/6 /*3/1

x = 5/6 * 3

x = 5/2 = 2 1/2

The correct result would be x * 1/3 inches = 5/6 inches

Please help fast!! Katrina has $3.60 worth of nickels and dimes. She has 46 coins in total. How many nickels and dimes does she

Igoryamba

Answer:

20 nickels and 26 dimes

Step-by-step explanation:

She has $3.60 in nickels and dimes
a nickel is $0.05 and a dime is $0.10
let n be the number of nickels and d be the number of dimes
thus the first equation is 3.6 = 0.05n +0.1d
If she has 46 coins then n + d = 46
then n = 46 - d
sub n = 46 - d into 3.6 = 0.05n +0.1d
3.6 = 0.05(46 - d) + 0.1d
3.6 = 2.3 -0.05d+0.1d
1.3 = 0.05d
26 = d
sub d = 26 into n+d=46
n+26=46
n=20
Check by subbing n=20 and d=26 into 0.05n +0.1d
0.05(20) +0.1(26)
1+2.6 = 3.6
