If the expression 3x + 2 is equal to 15 for some value of x, then which of the following is the value of 9x+5 for the same value of x?
(1) 40
(2) 46
(3) 44
(4) 50

44

Step-by-step explanation:

3x + 2 = 15

solve for x

x = 13/3

take this value and plug into the second expression and solve.

(9 x 13/3) + 5 = 44

the answer is 31.27mph

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
