Answer:
25
Step-by-step explanation:
12= 0.48x
x=12/0.48
x=25
A + b = 21 1/6 --> b = 21 1/6 - a
a - b = 4 3/6
a - (21 1/6 -a) = 4 3/6
a - 21 1/6 + a = 4 3/6
2a = 21 1/6 + 4 3/6
2a = 25 4/6
2a = 154/6
a = (154/6) / 2
a = (154/6) * (1/2)
a = 154/12
a = 12 10/12
a = 12 5/6
b = 21 1/6 -a
b = 21 1/6 - 12 5/6
b = 20 7/6 - 12 5/6
b = 8 2/6
Answer:
a = 12 5/6
b = 8 2/6
Double check:
a + b = 12 5/6 + 8 2/6
a + b = 20 7/6 ......(7/6 = 6/6 + 1/6)
a + b = 21 1/6
a - b = 12 5/6 - 8 2/6
a - b = 4 3/6

Step-by-step explanation:
I can't think of anything extra that I can add to this.
nickels / dimes = 21/13
This is as low as the ratio goes. There is no common factor.

im sorry its probably wrong, delete this if it is.
Answer: Answer is in the steps
Step-by-step explanation:
If the system of equations have the same slope and same y-intercepts then it means that they have infinitely many solutions.
if the system of equations have the same slope but different y-intercepts it means that they have no solution because they will never intersect but will always form parallel lines.
If the system of equations have different slopes and different y-intercepts or have same y-intercepts and different slopes it means that they have exactly on solution.
