A 6-pound bag of dog food costs $15. What is the unit price of the dog food? A. $15 per 6 pounds

B. $2.25

C. $2.50

D. $90 per pound

C

Step-by-step explanation:

  6.5 x=6.5

6.5 x 2 =15

0.5 x 6 =3

0.5 x 1=-.5

0.5 x 2=1.0

0.5 x 4=2.0

0.5 x 5=2.5

0.5 x 6=3.0 so 6 x 2= 12 adding 3 so 6.5 x 2=15

Hope it helps have a great afternoon:)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
