Answer:
see explanation
Step-by-step explanation:
A geometric progression has a common ratio r between consecutive terms
That is each term in the sequence is obtained by multiplying the previous term by r
Consider 4, 8, 16, 32
4 × 2 = 8
8 × 2 = 16
16 × 2 = 32
This is a geometric progression with r = 2
Consider 3, 6, 9, 12
3 × 2 = 6
6 × 2 = 12 ≠ 9
This is not a geometric progression
Consider 2, 6, 18, 54
2 × 3 = 6
6 × 3 = 18
18 × 3 = 54
This is a geometric progression with r = 3
Consider 1, 5, 12, 125
1 × 5 = 5
5 × 5 = 25 ≠ 12
This is not a geometric progression
Answer:
= 22/3 + 28/5
= ((22 × 5) + (28 × 3)) / (3 × 5)
= (110 + 84) / 15
= 194/15
= 194/15
= 12 14/15
.Adding Mixed Numbers:
Convert the mixed numbers into fractions.
Use the algebraic formula for addition of fractions: a/b + c/d = (ad + bc) / bd.
Your answer would be b,
you can use desmos and type the two equations in and graph for you :)
