[tex]\frac{x}{2}-\frac{2}{x+1}=1[/tex]
We have 2 denominators that we need to get rid of. Whenever there are the denominators, all we have to do is multiply all whole equation with the denominators.
Our denominators are both 2 and x+1. Therefore, we multiply the whole equation by 2(x+1)
[tex]\frac{x}{2}[2(x+1)]-\frac{2}{x+1}[2(x+1)] = 1[2(x+1)][/tex]
Then shorten the fractions.
[tex]\frac{x}{2}[2(x+1)]-\frac{2}{x+1}[2(x+1)] = 1[2(x+1)]\\x(x+1)-2(2)=1(2x+2)[/tex]
Distribute in all.
[tex]x^2+x-4=2x+2[/tex]
We should get like this. Because the polynomial is 2-degree, I'd suggest you to move all terms to one place. Therefore, moving 2x+2 to another side and subtract.
[tex]x^2+x-4-2x-2=0\\x^2-x-6=0\\[/tex]
We are almost there. All we have to do is, solving for x by factoring. (Although there are more than just factoring but factoring this polynomial is faster.)
[tex](x-3)(x+2)=0\\x=3,-2[/tex]
Thus, the answer is x = 3, -2
A ________ function specifies the relationship between the demand for a product LaTeX: x and the price of the product LaTeX: p.
Answer:
Price demand function
Step-by-step explanation:
The price demand function is the function in which there is a relationship between the demand and the price of the product
The Price demand function is
[tex]= Price \times demand[/tex]
[tex]= p \times x[/tex]
hence, the price demand function represents that there is a relationship that lies between the demand and the price

What is the volume of a cylinder, in cubic ft, with a height of 9ft and a base diameter
of 16ft? Round to the nearest tenths place
Answer:
Volume of cylinder is: Volume=1808.64 ft³
Step-by-step explanation:
Height of cylinder = 9 ft
Base diameter of cylinder = 16 ft
We need to find volume of cylinder .
The formula used is: [tex]Volume=\pi r^2h[/tex]
We need radius:
The radius = diameter/2 = 16/2 = 8 ft
Putting values and finding volume of cylinder
[tex]Volume=\pi r^2h[/tex]
[tex]Volume=3.14\times (8)^2\times (9) \\Volume=3.14\times 64\times (9) \\Volume=1808.64 \: ft^3[/tex]
So, Volume of cylinder is: Volume=1808.64 ft³

Workers install 840 chairs at a constant rate. After 8 days, the workers still have to install 360 chairs. How much time does it take to install the chairs from start to finish?
It took them 4 days to install 480 chairs which means if they were working at a constant rate they got 120 chairs installed daily. with 360 chairs left that means in 3 days they will finish. so overall, it took the workers 7 days to finish, or a week.

Answer:
You are faster. You are 0.25 min faster (15 seconds faster)
Step-by-step explanation:
you 19.5/3 =6.5 minutes per 1 mile
The friend 13.5/2 = 6.75 minutes per 1 mile
you run 1 mile in 6.5 minutes
the friend runs 1 mile in 6.75 min

The linear regression model y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold.
Using the model, approximate the temperature when there are 95 ice cream cones sold. Round your answer to the nearest tenth. When they sell 95 ice cream cones, the temperature is approximately _ °F.
Answer:
95.5 °F
Step-by-step explanation:
A linear regression model is used to represent the relationship between two variables in form of a linear equation. A linear regression line equation is in the form Y = a + bX, where X is the independent variable, Y is the dependent variable, b is the slope of the line and a is the Y intercept (the value of y when x = 0).
Given that x represents the temperature (°F) and y represents the number of ice cream cones sold.
We have the equation as y = 1.8x - 76.9.
Given a 95 ice cream cones sold, to find the temperature, we substitute y = 95 and find x:
y = 1.8x - 76.9
95 = 1.8x - 76.9
1.8x = 95 + 76.9
1.8x = 171.9
x= 95.5 °F
When they sell 95 ice cream cones, the temperature is approximately 95.5 °F

x=29/4=7.25The value of y varies directly with x. When the value y is ⅗, the value of x is 0.125. What is the value of x when the value of y is 12?
Answer:
x = 2.5
Step-by-step explanation:
y varies directly with x means the times that y increases, the times x increases and vice versa.
If y increases from 3/5 to 12 is being increased:
12 / 3/5 = 20 times
Thus, the value of x is being increased by definition, also 20 times. The value of x is:
x = 0.125 * 20 = 2.5
x = 2.5David Egil and frances share money in the ratio 2:7:9 Egil gets £85 more than David work out how much they each get ?
Answer:
David gets £34, Egil gets £119 and Frances gets £153.
Step-by-step explanation:
Let the amount of money David gets be 2x, Egil be 7x and Frances be 9x.
7x = 2x + 85
7x - 2x = 85
5x = 85
x = 85 ÷ 5
x = 17
David (2x) = 2 × £17
= £34
Egil (7x) = 7 × £17
= £119
Frances (9x) = 9 × £17
= £153
