Please Show Work. Line A and B are parallel lines transverse by line C. What is the measure of angle x?

The angle x is equal to 30°.

Step-by-step explanation:

We are given that

We can find out what angle is the supplement of 150° by setting up a simple equation.

Then, we can use the Corresponding Angles Postulate. This states that when two parallel lines are cut by a transversal, the angles that are corresponding (not a supplement) are congruent to each other.

Therefore, the angle that is to the top right of x is equal to 150°.

Finally, we need to find x. We can do this by using the same equation above and finding the supplement. We know this is 30°, so x = 30°.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
