Solve for x. 3x - 1 = 27 x = 26/3 x = 10 x = 28/3

x =

Step-by-step explanation:

Given

3x - 1 = 27 ( add 1 to both sides )

3x = 28 ( divide both sides by 3 )

x =

28/3

Step-by-step explanation:

3x-1=27

3x=27+1

3x=28

x=28/3

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
