Answer: Sarah found 10 shark teeth(3 + 7 = 10).
John found 5 shark teeth(10/2 = 5).
The total money they earned was $5 x 15 = $75.
Explanation;
Given that:
- $5 per shark tooth
- 15 total collected shark teeth
5 x 15 = 75, therefore the total money Sarah and John earned was $75.
The few sentences to end Sarah's story are: Sarah found 10 shark teeth for $50. John found 5 shark teeth for $25. They got $75 from their neighbor in total.

Answer:
f^-1(x) = √(6/(9 -x))
Step-by-step explanation:
The inverse function is the solution to ...
x = f(y)
x = 9 -6/y^2
x +6/y^2 = 9 . . . . . add 6/y^2
6/y^2 = 9 -x . . . . . subtract x
6/(9 -x) = y^2 . . . . . multiply by y^2/(9 -x)
y = √(6/(9 -x)) . . . . take the square root
Then the inverse function can be written as ...
f^-1(x) = √(6/(9 -x)) . . . . . . x < 9
Answer:
18
Step-by-step explanation:
you have to add 55 and 35 then divide the answer (90) by 1/5 then you get 18

The equation for the leg length, y is y = (P - 2x - 4)/2
The length of the leg "y" is 3 feet
a) Given the perimeter of the trapezoid expressed as:
P=2x + 2y + 4.
We are to make <em>y the subject of the formula </em>as shown:
P = 2(x+y) + 4
P - 2x = 2y + 4
P - 2x - 4 = 2y
Swap
2y = P - 2x - 4
y = (P - 2x - 4)/2
Hence the equation for the leg length, y is y = (P - 2x - 4)/2
b) Give that P = 26 feet and x = 8feet
y = (P - 2x - 4)/2
y = (26 - 2(8) - 4)/2
P = 26-20/2
P = 6/2
y = 3 feet
This shows that the length of the leg "y" is 3 feet

Answer:
x = 3/2
Step-by-step explanation:
Step 1: Write equation
-3(6x - 1) = -24
Step 2: Solve for <em>x</em>
<u>Distribute:</u> -18x + 3 = -24
<u>Subtract 3 on both sides:</u> -18x = -27
<u>Divide both sides by -18:</u> x = 3/2
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-3[6(1.5) - 1) = -24
-3[9 - 1] = -24
-3[8] = -24
-24 = -24
