0.05n + 0.1d = 3.10
n + d = 44
d = 44 - n
Substituting to the first equation:
0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26
Obtaining the value of nickels:
26 * 0.05 = 1.3
Therefore, the value of nickels that Bethany has is $1.30
She starts out with 3 dollars, and then she found 75 cents. 5 quarters are equal to $1.25.
The equation would be: (3 + 0.75) - 1.25
You can easily do this yourself. It takes more effort to create the question. Just multiply 22.854 by 5 then divide by 4 = 28.5675.

Step-by-step explanation:
Hello
Which expression is equivalent to 1/3 (5x + 3y) + 2/5y + 7 ?
a. 5/3x + 2/5y + 7
b. 5/3x + 7/5y + 7
c. 15x + 9 2/5y + 7
d. 15x + 2/5y + 7
1/3 (5x + 3y) + 2/5y + 7
= 5/3 x + y + 2/5 y + 7
= 5/3 x + 5/5 y + 2/5 y + 7
= 5/3 x + 7/5 y + 7
