So, to make a mixed number into an improper fraction, you have to multiply the whole number by the denominator and then add the numerator o that number.
2 and 7/10:
2x10=20+7=27/10!
<u>The answer would be B!</u>
I hope this helps!

The answer is B. You multiply the whole number (2) by the denominator (10) this gives you 20. Now add the numerator to 20 to get 27. The denominator stays the same.<span />

Diameter of 6x and height of 2x+5 what is the volume of the cylinder
ikadub [295]

Answer:

V = pi*x^2*(18x - 45)

Step-by-step explanation:

If the diameter is 6x and the height is 2x + 5, we know that the radius is 3x.

Plugging this info into the volume-of-a-cylinder formula V = pi*r^2*h, we get:

V = pi*(3x)^2*(2x - 5), or    V = pi*(9x^2)(2x -5), or:

V = pi*(18x^3 - 45x^2), or V = pi*x^2*(18x - 45)

Simplify the expression:<br> –9w+–6w+10w+8w
Y_Kistochka [10]

Final Answer: 3w

Steps/Reasons/Explanation:

It is common addition and subtraction because they all have w after the number. This means they are the same variable. A plus minus (+-) would be a minus (-).

<u>Step 1</u>: Simplify.

-9w - 6w + 10w + 8w
