If they're both equal $20 but there is many different ways to answer this like 19 plus 21
We can check by subbing in the values.
7x + 2y = -7
(7,9).....x = 7 and y = 9
now we sub
7(7) + 2(9) = -7
49 + 18 = -7
67 = -7 (incorrect)....therefore, (7,9) is NOT a solution for this equation
Given that the line segments NU and US can also be written as line segment NS then Point U would satisfy the Definition of Betweenness.
This simply means that Point U lies between Points N and S along the same line.
8 has been added to 11 to make it 19. 8 must be added to 24 to make it 32.
11 +t = 24
11 +8 +t = 24 +8
19 +t = 32
