Samantha cruz has 200 coins ( quarters and dimes) she has $44.00. Write a system of equations and determine how many quarters= _
tekilochka [14]

Answer: she has 40 dimes and 160 quarters

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a quarter is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

Let x represent the number of dimes that she has.

Let y represent the number of quarters that she has.

Samantha cruz has 200 coins ( quarters and dimes). This means that

x + y = 200

she has $44.00. This means that

0.1x + 0.25y = 44 - - - - - - - - - - - 1

Substituting x = 200 - y into equation 1, it becomes

0.1(200 - y) + 0.25y = 44

20 - 0.1y + 0.25y = 44

- 0.1y + 0.25y = 44 - 20

0.15y = 24

y = 24/0.15

y = 160

x = 200 - y = 200 - 160

x = 40

How are we supposed to graph this, it's easy the first number in the parenthesis is where it is on the x-axis, the second number in there is where it is at on the y-axis, that should help you so you can graph it yourself.

12y 2 y 2 +15y+26 ​ ÷ y 2 −9y 3y 3 +39y 2 ​ =start fraction, y, squared, plus, 15, y, plus, 26, divided by, 12, y, squared, end
Luda [366]

The equation is not typed properly, and it is difficult to understand. But it is clear that you are trying to determine the value of y that makes your equation undefined.

An fraction is undefined if it's denominator is zero, that is if it's of the form a/0.

The value that makes a fraction undefined is the value that makes the denominator vanish. The value that makes its denominator equal to zero.

Example:

1. (x - 3)/(y - 5) is undefined if

y - 5 = 0

Or y = 5

2. (3x² + 4xy + 6)/(x + 2)(y + 6)

If x + 2 = 0, or y + 6 = 0

That is if x = -2, or y = -6

You can use this idea to find the value of y that makes your equation undefined.
