The best way to solve this would be by the use of a table.
x) 1 2 3 4
y) 9 15 21 27
As you can see, the y value increases by 6 each time. Therefore d=6 or the common difference is 6
-2x + 4.4 = 23.8
Subtract 4.4 from both sides
-2x = 19.4
Divide both sides by-2:
X = -9.7
Answer: C. -9.7
1/7, because you divide both numerator and denominator by 8.
Answer:
-3/12

Answer:
x=100
Step-by-step explanation:
