A survey was given to students asking if they liked snowmobiles and/or skateboreds. Given that a student liked snowmobiles, what were the chances that the student liked skateboards?
A.64%
B.76%
C.50%
D.24%

your answer would be 12

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

- (2, -7)

- lines r and s and lines t and u must be parallel

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
