Get a common denominator of 9
1/3 *3/3 = 3/9
3/9 - 2/9
1/9
Let's solve step by step
So all we need to do is simplify the equation
<span><span>(<span>5x − 8</span>)</span><span>(<span>2x + 4</span>)

Answer:
6
Step-by-step explanation:
numbers/variables raised to the first power are equal to themselves
Answer: Jenna sold 280 and Becca sold 105 boxes.
Step-by-step explanation:
Let 3x be the number of cookies Becca sold.
Then, the number of cookies Jenna sold = 8x
Since Combined, they sold a total of 385 boxes of cookies.
So, 
So, Jenna sold 8(35) = 280 boxes
and Becca sold 3(35)= 105 boxes
Hence, Jenna sold 280 and Becca sold 105 boxes.
"The chemical is dispensed to completely fill 25 identical cylindrical containers"
So obviously the volume of each is 1/25 of the whole volume, right? So you know V for one of these cylinders.
"each with a radius of 5 in"
V = pi*r^2*h
<span>You know V. You know r. Plug them in. Solve for h. Should take one line.
</span><span>235,500 /25 = 9420 is the volume of 1 cylinder.
