A. 35% decrease yearly
B. 267.75
C. How much the computer is worth after 4 years
Vertical angles= XAW and UAY
complementary angles =XAW and XAZ
adjacent but not complementary or supplementary = XAZ and ZAY
supplementary = XAW and WAU
Answer:
x = 8 y = 8
Step-by-step explanation:
Multiply 2nd equation by -3 to get -6x - 3y = -72
Now 4x + 3y = 56
<u>-6x - 3y = -72</u>
-2x = -16
x = 8
Substitute x = 8 into the 2nd equation
2(8) + y = 24
16 + y = 24
y = 8
Check: Substitute the values into the 1st equation
4(8) + 3(8) = 32 + 24 = 56 So we have the correct values for x and y
Answer:
45
Step-by-step explanation:
If two lines are parallel and cut by a transversal, corresponding angles are congruent. Angle GEB and angle EFD are corresponding so they are congruent so you can set them equal to each other and solve.
2x - 30 = x + 15 (add 30 to both sides, subtract x from both sides)
X = 45
