First let's write it down,

x + (2x - 3) + (3x - 5)

Then remove the parentheses

x + 2x - 3 + 3x - 5

first combine the x + 2x = 3x to obtain: 3x - 3 + 3x - 5

then combine the 3x + 3x = 6x to obtain:

6x - 3 - 5

rewrite 6x - 3 - 5 as 6x + (-3) + (-5)

And the answer would be 6x + (-8) =

I hope my answer helped you

Your equation might look like this,
Since the ticket is $8, and her budget is 50, your gonna have to divide.
Then the remaining answer would be, 6.25.
So, your equation= $50/$8=6.25
Your answer is 6, 6 tickets can be bought with the remainder of 0.25 cents.

What is the surface area of the cylinder with height 7 cm and radius 5 cm? Round

nalin [4]

Answer:

376.991 cm²

Step-by-step explanation:

$SA_{cylinder} = 2\pi r^{2} + 2\pi rh$

Surface Area = 2π(5²) + 2π(5)(7)

= 50π + 70π

= 120π

= 376.9911184... ≈ 376.991

<h2>Derive Surface Area of A Cylinder</h2>

If you take a look at a net of a cylinder, you can see it is composed of two circles(bases) and a rectangular strip with the length of the diameter of the circle

The formula for the area of a circle = πr², and since there are 2, it is 2πr²

The formula for circumference of a circle = 2πr, and since we are multiplying that by the height by the height of the cylinder, it is 2πrh

∴ 2πr² + 2πrh

All you had to do was plug in the value for c or b and solve. You can tell this is most likely correct because you see patterns for both variables. C is going up by threes, while b is going up by nines.
