pashok25 [27]

Answer:the number of cars that were washed is 50

Step-by-step explanation:

Let x represent the number of cars that members of a senior class.

Let y represent the number of pick-up truck or a sport utility vehicle that members of a senior class.

They charged $3 to wash a car and $5 to wash a pick-up truck or a sport utility vehicle and they earned a total of $275. This means that

3x + 5y = 275 - - - - - - - - -- - -1

They washed a total of 75 vehicles. This means that

x + y = 75

Substituting x = 75 - y into equation 1, it becomes

3(75 - y) + 5y = 275

225 - 3y + 5y = 275

- 3y + 5y = 275 - 225

2y = 50

y = 50/2 = 25

Substituting y = 25 into x = 75 - y, it becomes

x = 75 - 25 = 50

2. Which of the following ordered pairs (x,y) satisfies the system of equations below?
nataly862011 [7]

Answer:

x=2, y=-2

(2, -2)

Step-by-step explanation:

x + y = 0

3x - 2y = 10

3x - 2(0 - x) = 10                  ( 2(0 - x) = -2x )

3x - (-2x) = 10                      ( y = -x )

3x + 2x = 10

5x = 10

x = 2

Hope i helped, feel free to ask questions :D
