Solve by elimination ie eliminate x or y from the equations by performing operations on them.
first label the equations , to follow the process.
x - y = 5 ----------------(1)
x+ y = 3 ----------------(2)
If (1) and (2) are added then y will be eliminated.
(1) + (2) gives : 2x = 8 → x = 4
now substitute this value of x into either of the 2 equations and solve for y.
let x = 4 in (1) : 4 - y = 5 → -y = 1 → y = -1
check in (1) : 4-(-1) = 4+1 = 5
check in(2) : 4 - 1 = 3
So your answer is x = 4 , y = -1
Answer: WZ
The sequence ABCD has AD as the first and last letters of that sequence, so this pattern applies to WXYZ as well to pull out WZ. Angle A pairs up with angle W because they are both the first letters of the sequences. These angles are congruent from the fact that the parallelograms are similar. The same can be said for angle D and angle Z.
note: WZ is the same as ZW. The order doesn't matter when it comes to labeling segments based on endpoints.
im assuming you need to know the length of the 7 equal bits of ribbon. the original length of ribbon - the length of ribbon left over = 7x
170.9-16.2=154.7. 154.7/7=x = 22.1
each length of ribbon was 22.1 inches long
20/2=10 because the formula for acceleration is velocity or speed (20) divided by time (2)
