Answer is: x=3
Add the two equations together to eliminate y from the system.
Then divide each term by 5 and simplify.
If you were to make your own measurements, your significant digits should include all of the measurable digits (the digits that correspond to the marks on the ruler) as well as one estimated position beyond the smallest measureable digit (the 5 in 3.5 cm, and the 2 in 3.52 cm).
Answer:
<1 and <8 are alternate exterior angles
Step-by-step explanation:
Alternate means on the opposite side of the transversal
Exterior means outside the parallel lines
<1 and <8 are alternate exterior angles
3(a+b) and 3a+b: not equivalent
4(x+2y) and 8y+4x: equivalent
