Answer:
12
Step-by-step explanation:
in this problem there is A+b=15
A=9
B=12
<span>Add both the result (1×3 + 1×3) = 6 and write down to the left of 9 (result ofstep 1).

Answer:
Step-by-step explanation:
I think 47 but i might b wrong lol
This is a problem of
system of linear equations in two variables. This concept of mathematics is very useful in real-life problems. You can solve a system by finding the solution. A
solution of a system are the values of the variables that satisfies each equation in the system. So by knowing these concepts we can get a system of equation by analyzing each statement step by step, that is:
1. Alice has a total of 12 dimes and nickels.
Let the variables:
1st. Equation:
<span>
2. She has 2 more nickels than dimes
2nd Equation:
Therefore our system of linear equations is:
</span>
Conclusion:<span>Alice has
5 dimes and
7 nickels. </span>
