Members of a senior class held a car wash to raise funds for their senior prom. They charged $3 to wash a car and $5 to wash a p
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

There are 5 red roses, 3 yellow roses, and 8 white roses in a tray. If Stephanie picked 2 roses one after the other without repl
Wewaii [24]
So probility is (disired outcomes) divided by (total possible outcomes) so

1st one is white roses
8 white roses so 8 is disired
total=5+3+8=16
8/16=1/2
then without replacing them
red=5
total possible=16-1 since 1 picked
5/15=1/3
then multiply the probatilities

1/2 times 1/3=1/6
it is a 1 in 6 probability
