Which represents the solution set of 5 (x + 5) less-than 85 x less-than 12 x greater-than 12 x less-than 16 x greater-than 16

For this case we must find the solution of the following inequality:

Applying distributive property on the left side of inequality we have:

Subtracting 25 from both sides of the inequality we have:

Dividing between 5 on both sides of the inequality we have:

Thus, the solution is given by all values of x less than 12.

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
