Answer:
50/1, 100/2, 250/5, 400/8
While solving an equation the first step is to get the variable (x) alone on either side.
2.3 x - 1.6 = 8.8 - 2.9 x
+ 1.6 +1.6
2.3 x = 10.4 - 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
-8.8 - 8.8
2.3 x - 10.4 = 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+2.9 x + 2.9 x
5.2 x -1.6 = 8.8
Answer:
857
Step-by-step explanation:
70th term = a + d(n-1)
d= 29-17=12
a=29
n-1 = 69
70th term = 29 + 12×69
= 29 + 828
= 857
