Mary has 15 points with the total value of $1.75 if the coins are nickels and quarters how many of each kind are there
torisob [31]

Answer:

The number of nickel coins is 10 and the number of quarter coins is 5

Step-by-step explanation:

<u><em>The correct question is</em></u>

Mary has 15 coins with the total value of $1.75 if the coins are nickels and quarters how many of each kind are there

Let

x ----> the number of nickel coins

y ----> the number of quarter coins

Remember that

1\ nickel=\$0.05

1\ quarter=\$0.25

we know that

Mary has 15 coins

so

x+y=15 -----> equation A

The total value of the coins is $1.75

so

0.05x+0.25y=1.75 ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (10,5)

therefore

The number of nickel coins is 10 and the number of quarter coins is 5

When you mix two colors of paint in equivalent ratios, the resulting color is
vredina [299]

Answer:

Step-by-step explanation:

From the given table,

To prepare a mixture of a paint, two paints of different shades have been added in the same ratio,

Since, 2 cups of blue paint are mixed with 10 cups of yellow paint

Therefore, ratio in which these shades have been added = \frac{\text{Pink}}{\text{Blue}}

                                                                                                = \frac{10}{2}

                                                                                                = \frac{5}{1}

                                                                                                = 5 : 1

For 1 cup of blue paint number of cups of yellow paint required,

\frac{x}{1}=\frac{5}{1}

x = 5 cups

For 3 cup of blue paint number of cups of yellow paint required,

\frac{x}{3}=\frac{5}{1}

x = 15 cups

Cups of blue paint                Cups of yellow paint

            2                                             10

            1                                               5

            3                                              15
