Alice has a total of 12 dimes and nickels. She has 2 more nickels than dimes

valkas [14]

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:

$D: Dimes \\ N:Nickles$

1st. Equation:

$D+N=12$

<span>2. She has 2 more nickels than dimes

2nd Equation:

$N=D+2$

Therefore our system of linear equations is:

</span> $(1) \ D+N=12 \\ (2) \ N=D+2 \\ \\ Substituting \ (2) \ in \ (1): \\ D+(D+2)=12 \therefore 2D=10 \therefore D=5 \\ \\ Solving \ for \ N \ in \ (2): \\ N=5+2=7$

Conclusion:

<span>Alice has 5 dimes and 7 nickels. </span>

Answer 5 plz!! Due tomorrow!

Hey!

So, the denominator tells us how many pieces there are in the pizza. (4)

4 × 1 = 4 --- That's not enough for 11 people, if each person is supposed to get 1 slice.

4 × 2 = 8 --- Still Not Enough.

4 × 3 = 12 --- This is more than enough. 11 people can each have 1 slice.

So, your answer is: Cyrus should order 3 pizzas.
