Answer:
7/10, 14/20, 21/30, 28/40, 35/50, 42/60, 49/70, 56/80, 63/90, 70/100, 77/110, 84/120, 91/130, 98/140, 105/150, 112/160, 119/170, 126/180, 133/190, 140/200,
Step-by-step explanation:
x=-8 y=6
Add the two equations together. This cancels the x and gets us y=6
Then substitute y in more the first equation which gets us -8
You can look at it and see that 1/3 is added to each term. The common difference is 1/3. If you want to be be more formal,
d = d4 - d3
d = 0 - - 1/3
d = 0 + 1/3
d = 1/3
90
3/2(60) = 90
VW = 23
Since VU is 31 and part of it (WU) is 8, the remaining (VW) would be 31-8 = 23.
