Jennifer has 25 coins with a total value of $4.25. The coins are quarters and nickels. How many of each does she have?
andrezito [222]

Answer:

15 quarters and 10 nickels

Step-by-step explanation:

q+n=25

0.25q+0.05n=4.25

multiply the first equation by -0.25 and add the second equation to it

-0.25q-0.25n=-6.25\\0.25q+0.05n=4.25
________________
                -0.2n=-2

n=\frac{-2}{-0.2} =10   has 10 nickels

q=25-n=25-10=15  has 15 quarters

10(.05) +15(0.25) = 0.5 + 3.75 = 4.25

Hope this helps

Adelle solved the equation 4x/7 - 6 = -20 as shown. Fill in the correct justification for each step.
Stells [14]

From the equation solved, it can be deduced that the value of x will be -5.

<h3>How to solve an equation</h3>

From the information given, the equation is 4x/7 - 6 = -20. The step to solve it is given below:

4x/7 - 6 = -20

Cross multiply

4x = -20(7 - 6)

4x = -20(1)

4x = -20

Divide both side by 4

4x/4 = -20/4

x = -5

In conclusion, the value of x is -5.
