Hi,
Step-by-step explanation:
Let say n the number of nickels
4*n the number of quaters.
Let's calculate in cents:
n*5+4*n*25=1260
5n+100n=1260
105*n=1260
n=12 (number of nickels)
4n=48 (number of quaters)
Proof: 12*5+48*25=1260
Answer is equation B
Answer:
No solution for the given algebraic expression.
Step-by-step explanation:

Solve: 
Now put every terms that contains variables on one side of the equation and those terms on the other side which does not contains the variable.

Combine like terms:

which is not true.
therefore, the given expression have NO SOLUTION.
Answer:
a number=x
equation= x/-8=15
Step-by-step explanation:
7x+6x=650
13x= 650
Divide by 13
X= 50
She saves 7(50)= 350
She speeds 6(50)=300
