Hello, Marymack!
We know that in a geometric sequence defined by

and

, the sum can be calculated the following way:
Answer: 165/11 =
(3 × 5 × 11)/11 =
((3 × 5 × 11) ÷ 11) / (11 ÷ 11) =
(3 × 5)/1 =
15/1 =
15
Step-by-step explanation:
Answer:
n = (7/3)t
Step-by-step explanation:
Represente the unknown number by n. Then write the statement symbolically, as:
(3/7)n = t
and then solve the above equation for n by multiplying both sides by (7/3):
n = (7/3)t
He tried about 10
74% of 14 is 10.36
Round it to a whole number
=10
