The probability of it not having a defective wheel is 0.985 because 1 - 0.015 is 0.985.
Answer:
x=90 degrees
y=142 degrees
z=128 degrees
Step-by-step explanation:
is that a variable of x or a multiplication sign?
1) x+y = 170
x-y = 26
2) Subtract the two equations from each other. Doing this you get 2y = 56.
So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.
x-28 = 26
x = 54
3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).
Answer:
Step-by-step explanation:
x=−10, y=−3
x=10, y=7
y=7,x=10
y=−3,x=−10
