Ferrell has 9 nickels and some quarters in his pocket. The value of his coins is $3.70. Which equation can be used to find the number of quarters, q, Farrell has in his pocket?

Step-by-step explanation:

Given that:

Number of nickels with Ferrell = 9

Number of quarters =

Value of coins = $3.70

To find:

The equation to find the number of quarters.

Solution:

Value of a nickel = 5 quarters = $0.05

Value of 9 nickels =

Value of a quarter = $0.25

Value of quarters = $0.25

Total value of coins = Value of 9 nickels + Value of quarters

So, the answer is, number of quarters available with Ferrell = 13

The equation to be used to find the number of quarters, :

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

5050
