2. A high-school track team sold tickets for a car wash to raise money for equipment. Tickets sold for $5 for cars and $8 for vans. The team sold 200 tickets. They raised a total of $1150.
The linear system that represents this situation is: x = cars and y = vans
x + y = 200
5x + 8y = 1150
How many cars and how many vans did they wash? Show all work.
please help it's for a test and I can't figure this out please ​

what are you trying to solve here

step-by-step explanation:

answer: apothems is your answer

step-by-step explanation: hope u get it right

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
