Solve this system of equations

x = 3z − 5
2x + 2z = y + 16
7x − 5z = 3y + 19

Select the appropriate response
A) 1, y = −2, z = 3
B) 5, y = −4, z = 1
C) 5, y = −8, z = 6
D) 4, y = −2, z = 3

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

Average acceleration: i have no idea how to do this.

1) in triangle the, what is the measure of angle t (in degrees)? 2) in triangle bat, the measure of angle b is 66∘, and the measure of angle t is 77∘.what is the measure of the exterior angle at a (in degrees)?
