A + b +c = 75; where a is the greatest number; b is the middle number; c is the least number;
a = 2 * c;
b = 3 + c;
then, 2 * c + 3 + c + c = 75 => 4 * c = 72 => c = 72 / 4 => c = 18 => a = 2 * 18 => a = 36; b = 3 + 18 => b = 21;
Answer:
A
Step-by-step explanation:
The explicit formula for a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
The recursive formula gives a term in the sequence by multiplying the previous term by r
Given the recursive formula
a₁ = - 6
= 
(
)
with r =
Then explicit formula is
= - 6
→ A
I don’t see the image can you please add one to the comments so I can answer it. Thanks
Answer:
1) 5/6 + 2/5 = 37/30 2) 1/6 - 1/10 = 1/15
Step-by-step explanation:
1) 5/6 + 2/5
25+12/30
= 37/30
2) 1/6 - 1/10
5-3/30
2/30
simplify the fraction
= 1/15
