one-third of the fish in Liam's fish tank were added today. Half of the other fish were a gift to Liam last week. the other 9 came from Liam's old fish tank. How many fish are in the tank? What is the difference between the number of fish Liam had in his old tank and the number he has now?

Answers

Answer 1

Answer:

Answer: Total fish are 27, difference is 18

Step-by-step explanation:

Given: one-third of the fish in Liam's fish tank were added today. Half of the other fish were a gift to Liam last week. the other 9 came from Liam's old fish tank.

To Find: Number of the fish in the tank, difference between the number of fish Liam had in his old tank and the number he has now.

Solution: Let the total fish in tank be = x

total fish added today = $(1)/(3)* \text{x}$

Total fish left = $\text{x}-(1)/(3)\text{x}$ = $(2)/(3)\text{x}$

Fish gifted to him last week = $(1)/(2)*(2)/(3)* \text{x}$

= $(1)/(3)\text{x}$

Fish left = $(2)/(3)\text{x}$ - $(1)/(3)\text{x}$

$(1)/(3)\text{x}$

now,

fish left in the tank are = $(1)/(3)\text{x}$

fish from liam's old tank = 9 = fish left in the tank

$(1)/(3)\text{x}$ = 9

$\text{x}$ = $27$

Total fish in liam's new tank= $27$

difference between the number of fish Liam had in his old tank and the number he has now

= $27-9=18$

Total Fish in Liam's new tank are 27 and difference between the number of fish Liam had in his old tank and the number he has now is 18.

Answer 2

Answer: There are 54 fish in the tank. The difference between the fish he had and the fish he has now is 45 fish. 1/3=2/6 1/2=3/6. I converted so there is a common denominator. 2/6+3/6=5/6. That leaves 9 fish. 9 fish is 1/6. So if I multiply 9 by 5 that gives me the rest of the fish, which is 45. Then, I add that together to get 54.

The solution graph provided shows a shaded region below the line y = x + 2. This line has a slope of 1 and a y-intercept of 2.

To determine the correct system of linear inequalities represented by the graph, we need to consider the shading and the type of inequalities involved.

Looking at the shaded region below the line, we can see that it includes the points that satisfy the inequality y ≤ x + 2. This means that y is less than or equal to x + 2.

Therefore, the correct system of linear inequalities represented by the solution graph is:

y ≤ x + 2.

Option C: -5 < x < 5 and y ≤ x + 2 satisfies this condition.

Sales tax in the state of Florida is 7%. Bob purchased a coat that was marked $350.00. What is the total bill including tax?

Answers

To find the tax, you multiply the tax rate by the amount to be taxed, so...350 × 7%
350 × .07 = $24.50

This is the amount of tax. Now add it to the original price for the total cost.

$350.00 + $24.50 =

$374.50
