Eva is buying Comet Goldfish to add to her aquarium. Each fish costs $0.21, and Eva has $3.00. Which of these represent the inequality and/or solution for how many Comet Goldfish Eva can buy?

3.00 ≥  0.21 x

The number of Comet Goldfish Eva can buy = 14.

Step-by-step explanation:

Let 'x' be the number of Comet Goldfish.

The cost of each fish = $0.21

Then , the cost of 'x' Comet Goldfish = $0.21 x

Total amount Eva has = $3.00

Now , the required inequality is

Total amount Eva has  ≥ Cost of 'x' Comet Goldfish

3.00 ≥  0.21 x

To find x , we divide both sides by 0.21  , we get

14.2857142857 ≥x

⇒x= 14     [∵ x cannot be a decimal number as it represents the number of                             fish.]

Hence, the number of Comet Goldfish Eva can buy = 14.

536

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
