spin [16.1K]3 years ago
4 0
\frac{3}{x+2} =  \frac{4}{x+1} \\ \\ 3(x + 1) = 4(x + 2) \\ \\ 3x + = 4x + 8 \\ \\ 3 = 4x + 8 - 3x \\ \\ 3 = x + 8 \\ \\ 3 - 8 = x \\ \\ -5 = x \\ \\ x = -5 \\ \\

The final result is: x = -5.

As of a certain date, there had been a total of 14,649 performances of two shows on Broadway, with 2389 more performances of Sho
Naddik [55]

Subtract the difference:

14,649 - 2389 = 12,260

Divide that by 2

12,260 / 2 = 6,130

That is the number of shows for B.

For A add the 2,389 to the number of shows for B

2389 + 6130 = 8,519

Show A = 8,519

Show B = 6,130

What does it mean by n? thanks
ra1l [238]
When you solve the inequality, you will write down all the x values that satisfy the inequality but they have to be integers. The n is x, it is just a common variable used to help describe what kind of numbers they want.

A cylinder circumference 11 pi in and height 10in. What is the volume of the cylinder?
Fiesta28 [93]

Answer:

950.455in^3

Step-by-step explanation:

Given data

Circumference= 11π

Also, the expression for circumference is

C=2πr

11π=2πr

solve for r

r= 11π/2π

r= 5.5in

Given that the Height h= 10in

The expression for the volume is

V= πr^2h

V=3.142*5.5^2*10

V=3.142*30.25*10

V=950.455 in^3

Hence the volume is

950.455in^3

How to solve k(a)=4a + 2: find k(a-3)
uysha [10]

If you meant to say k=(-3)

First thing you would do is plug in the (-3) to a

Your equations would look like this:

k(a) = 4(-3) + 2

You would multiply 4 × -3, giving you -12.

k(a) = 12 + 2

Then you would add 12 + 2, giving you 14.

k(a) = 14

k(a) would equal 14.
