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:

$D+N=12$

2. She has 2 more nickels than dimes

2nd Equation:

$N=D+2$

Therefore our system of linear equations is:

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

Conclusion:

Alice has 5 dimes and 7 nickels.

Hank has a bottle of diluted syrup that is 60% maple syrup and a bottle of pure syrup that is 100% maple syrup in his restaurant

Nezavi [6.7K]

Answer:

62.5 oz of 100%

Step-by-step explanation:

Let p represent the number of ounces of pure syrup. Then (100-p) is the number of ounces of 60% syrup. The amount of maple syrup in the desired mix is ...

p +0.60(100 -p) = 0.85(100)

0.40p +60 = 85 . . . . . . . . . . . simplify

0.40p = 25 . . . . . . . . . . subtract 60

p = 62.5 . . . . . . . . . divide by 0.4

62.5 ounces of pure syrup should be mixed with the diluted syrup to make 100 ounces of 85% maple syrup.

_____

The other 37.5 ounces will be 60% syrup.
