Nick's Printing Press promptly sold 5-cent pencils and 10-cent pens to the public. It sold 1000 writing utensils and took $74.50

galben [10]

Answer:

490 pens
510 pencils

Step-by-step explanation:

Let p represent the number of pens Nick sold. Then the revenue is ...

0.10p +0.05(1000 -p) = 74.50

0.05p = 24.50 . . . . . . eliminate parentheses, subtract 50

p = 490 . . . . . . . . . . . . multiply by 20

The number of pencils sold is then ...

pencils = 1000 -490 = 510

Nick's Printing Press sold 490 pens and 510 pencils.

Find the surface area of the cube.

Mrac [35]

<h3><u>Given</u>:-</h3>

$\rightarrow$ Side(a) of the cube = $\sf{\frac{1}{3}ft}$ .

$\rightarrow$ Surface Area of the cube with side $\sf{\frac{1}{3}ft.}$

<h3><u>Formula Used</u>:-</h3>

$\rightarrow$ Surface area of cube = $\sf{6a^2}$

<h3><u>Solution</u>:-</h3>

$\rightarrow$ Surface area of cube = $\sf{6a^2}$ (putting the value of a from the above given)

$\rightarrow$ $\sf{=\:6×(\frac{1}{3})^2}$

$\rightarrow$ $\sf{=\:6×\frac{1}{9}}$

$\rightarrow$ $\sf{=\:\frac{6}{9}}$

$\rightarrow$ $\sf{=\:\frac{2}{3}ft^2}$

Therefore, surface area of the given square = $\sf{=\:\frac{2}{3}ft^2}$

How do you solve a two step equation

Schach [20]

Isolate the variable, and see what kind of equation it is. if it's adding, let's say, then add one number to itself. this cancels it out, so it's taken care of. next, add that same number to the second one, and take the result. you should be able to subtract that from the answer i believe, it's been a while since I've done these so it might not be spot on
