Johan and Enik are playing with chips. In each round, a player can win a maximum of 5 chips from his opponent. Whoever has the most chips at the end of the game is the winner. At the beginning of a certain round, Johan thinks: "If I can win 5 chips, then I have three times more than Erik" Erik, in turn, thinks: "If I can get 5 chips out of Johan, then I will have twice that. if he". How many chips did each start in that round?
What is the inverse function of f(x)=-6x-7?
f-1(x) =
Answer:
[tex]f^{-1}(x)[/tex] = [tex]-\frac{x+7}{6}[/tex]
Step-by-step explanation:
y = -6x-7?
x = -6y - 7
Add 7 on both sides
x + 7 = -6y
Divide -6 on both sides
y = [tex]-\frac{x+7}{6}[/tex]
Us plans to install a handrail around a rectangular skating rink. One of the rink's sides is 40 meters long and one of the rink's width is 20 meters wide. How many meters of handrail does Gus need to cover the perimeter of the rectangular skating rink?
Given :
Length of rink, L = 40 meters.
Width of rink , W = 20 meters.
To Find :
How many meters of handrail does Gus need to cover the perimeter of the rectangular skating rink.
Solution :
We know, perimeter is given by :
[tex]P=2(L+W)[/tex]
Putting value of L = 40 meters and W = 20 meters, in above equation , we get:
[tex]P=2(40+20)\ meters\\\\P=120\ meters[/tex]
Therefore, the perimeter of the rectangular skating rink is 120 meters.
Hence, this is the required solution.

Answer:

Step-by-step explanation:
The solution to the inequality is 2 ≤ x < 8.
What is meant by mathematical inequality ?A mathematical inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
Here,
The mathematical inequality given is,
8 ≥ -5x + 2 > -38
Subtracting 2 from all sides,
-8 - 2 ≥ -5x + 2 - 2 > -38 - 2
So, -10 ≥ -5x > -40
Dividing by -5 on all sides,
Therefore,
2 ≤ x < 8
That means the inequality is reserved.
Hence,
The solution to the inequality is 2 ≤ x < 8.

Answer:
g = 6
Step-by-step explanation:
3.8g + 8 = 1.8g + 20
Subtract 1.8g from both sides;
2g + 8 = 20
Subtract 8 from both sides;
2g = 12
Divide both sides by 2;
g = 6
You can check if the value of g is correct by plugging in the value of g to the equation. If your check does not it doesn't mean your answer is not correct because sometimes it can be a no solution equation which means that there is no solution to the equation.
Check:
3.8(6) + 8 = 1.8(6) + 20

A model of a tractor-trailer is shaped like a rectangular prism and has a width of 2 in., a length of 11 in., and a height of 4 in.. The scale of the model is 1 font size decreased by 10 : font size decreased by 10 34. How many times the volume of the model is the volume of the actual tractor-trailer?
Answer:
The volume of the actual tractor-trailer is 2992 in³
Step-by-step explanation:
To determine how many times the volume of the model is the volume of the actual tractor-trailer,
First, we will determine the volume of the model tractor-trailer.
Since, the model tractor trailer is shaped like a rectangular prism, the volume of the model tractor-trailer can be calculated using the formula for volume of a rectangular prism.
Volume of rectangular prism = length × width × height
From the question,
length = 11 in
width = 2 in
and height = 4 in
∴ Volume of model tractor-trailer = 11 in × 2 in × 4 in
Volume of model tractor-trailer = 88 in³
From the question,
The scale of the model is 1 font size decreased by 10 : 34 font size decreased by 10.
That is 1 : 34
Then, if the the volume of the actual tractor-trailer is y, we can write that
[tex]\frac{1}{34} = \frac{88}{y}[/tex]
Then,
y = 88 × 34
y = 2992 in³
Hence, the volume of the actual tractor-trailer is 2992 in³.

Which equation represents the nth term of the sequence {2, -1, -4, -7,...}?
Answer:
[tex]a_{n}[/tex] = 5 - 3n
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 1 - 2 = - 4 - (- 1) = - 7 - (- 4) = - 3
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 3 , thus
[tex]a_{n}[/tex] = 2 - 3(n - 1) = 2 - 3n + 3 = 5 - 3n

Answer: x = -9
Step-by-step explanation:
3x + 2x = 5x
7x + 5 - 5 = 5x - 13 - 5
Subtract 5 from both sides
7x + 5 - 5 = 5x - 13 - 5
simplify
7x = 5x - 18
Subtract 5x from both sides
7x - 5x = 5x -18 - 5x
simplify
2x = -18
divide both sides by 2
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-18}{2}[/tex]

Two pounds of apples cost $3.98. Six pounds cost $11.94.
What is the rate of change for the cost of apples?
Answer:
$7.96
Step-by-step explanation:
= $11.94-$3.98
= $7.96
Iif two pounds of apples cost $3.98. Six pounds cost $11.94 then 2 pounds is the rate of change for the cost of apples
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Two pounds of apples cost $3.98
Six pounds cost $11.94.
We need to find the rate of change for the cost of apples
The cost changes from $ 3.98 to $ 11.94
while the number of pounds of apples changes from 2 to 6.
Thus the rate of change is
11.94-3.98/6-2
2 pounds
Hence, if two pounds of apples cost $3.98. Six pounds cost $11.94 then 2 pounds is the rate of change for the cost of apples
