Will give brainliest for the correct answer.

which ordered pair (a, b) is a solution to the given system?

2a-5b=1
3a+5b=14

(1, 3)
(3, 1)
29/5 , 15
(15 , 29/5)

And employee salary increased by $4500 which represents a 15% raise what is the rate of the increase

Match each equation with the operation you can use to solve for the variable. 1 subtract 10 2 divide by 10 3add 18 4add 10 5 subtact 18 6multiply by 5. 7multiply by 10. a 5 = 10p b p + 10 = 18 c p + 18 = 5 d 5p = 10

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.
