A type of fish for your aquarium costs $3 each. You can spend at most $21. How many of these fish can you buy? Write an inequality to model the problem. Then solve the inequality to find the number of fish.
Let f be the number of fish you can buy. Which inequality models the problem?
A.
3 f less than or equals 21
B.
3 f greater than or equals 21
C.
f plus 3 less than or equals 21
D.
f plus 3 greater than or equals 21

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

step-by-step explanation:

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
