Theresa has $12 in nickels and quarters. If she has the same number of each kind of coin, how many nickels and quarters does she

postnew [5]

Answer: She has 40 nickels and 40 quarters .

Step-by-step explanation:

Let be "n" the number of nickels Theresa has and "q" the number of quarters Theresa has.

You know that she has a total of $12 in nickels and quarters. In cents, this is:

$\$12*100=1,200\ cents$

Then, based on this you can write the following expression:

$5n+25q=1,200$

Since $n=q$ , you can rewrite it as:

$5n+25n=1,200$

Solving for "n", you get:

$30n=1,200\\\\n=\frac{1,200}{30}\\\\n=40$

Therefore she has 40 nickels and 40 quarters .

Solve the equation<br>algebra 2<br><br>-6=3x-6y<br>4x=4+5x

Talja [164]

3x = 6y - 6
x = 2y - 2

4 ( 2y - 2 ) = 4 + 5 ( 2y - 2 )
8y - 8 = 4 + 10y - 10
2y = - 2
y = - 1

x = 2 ( - 1 ) - 2
x = - 4
