Answer:
a) x = 2
b) x = 4
Step-by-step explanation:
a = (b₁ + b₂)/2 * h
----------------------------
a)
48 = (10 + x)/2 * 8
Divide both sides by 8
6 = (10 + x)/2
multiply both sides by 2
12 = 10 + x
Subtract 10 from both sides
2 = x
x = 2
---------------------------------
b)
18 = (7 + 2)/2 * x
18 = 4.5 * x
divide both sides by 4.5
4 = x
x = 4
The answer A.the solution is (5,-2) definitely works because 5+-2=3 and 5--2=7 not sure if there's infinite number of solutions tho
Answer:
75, 89, 91, 105, 107, 121, 123, 137
Step-by-step explanation:
If you analyze how much each number is increased, you will notice it alternates between adding 2, then adding 14:
11 + 14 = 25.
25 + 2 = 27.
27 + 14 = 41.
41 + 2 = 43.
43 + 14 = 57.
57 + 2 = 59.
59 + 14 = 73.
That means you can simply, finish the pattern, alternating between adding 2 and 14. Then you will get these answers.
