Five friends go out to dinner together. the meal comes to $90. each friend contributes the same amount of money to pay the bill. how much money does each friend contribute? use the five-step solving plan

x=18

Step-by-step explanation:

1)First make the equation

x+x+x+x+x=90

2)Now rid of alike terms

5x=90

3)Now divide both sides by 5

x=18

4) Now check the answer

18+18+18+18+18=90

90=90

5) You've got the answer x=18

Hey there!!

Total cost - $90

... There are 5 people and everyone pays the same.

... Person + person + person + person + person = 90

... 5 ( person ) = 90

... person = 90 / 5

... person = 18

Hence, each person pays $18.

Hope my answer helps!!

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

(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
