The height is 17, the length is 2w+4 and the width = w.
So you need to know V=2720^3= (17)(2w+4)(w)
Now you just combine and solve for W
hope this helps

So.. if the width is  say  "w", twice the width will then be 2*w or 2w
and 4 greater than that, => 2w + 4

thus   \bf \qquad \qquad \textit{volume of a rectangular prism}\\\\
V=l\cdot w\cdot h\qquad 
\begin{cases}
l=length\\
w=width\\
h=height\\
-------\\
h=17\\
l=2w+4\\
V=2,720
\end{cases}\implies 2720=(2w+4)(w)(17)

solve for "w"

All simplified answers for 6x+1-(3x-1)
sertanlavr [38]

Answer:

Step-by-step explanation:

Simplify ——————

3x - 1

Equation at the end of step 1 :

(6x - 1)

y - ———————— = 0

3x - 1

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using (3x-1) as the denominator :

y y • (3x - 1)

y = — = ————————————

1 (3x - 1)

A company placed $500,000 in three different investment plans.
Paha777 [63]

Answer:

B. $200,000

Step-by-step explanation:

Let x be the amount placed at 5.5%

3x is the amount placed at 5%

This leaves the rest for the 4.5 %   500000- x - 3x = 500000-4x

Assuming simple interest

I = PRT where I is interest, P is principle, rate is rate and t  is time

Interest for the 5.5% for 1 year is

I = x * .055 * 1 = .055x

Interest for the 5.% for 1 year is

I = 3x * .05 * 1 = .15x

Interest for the 4.5% for 1 year is

I = 500000-4x * .045 * 1 = 22500 - 0.18 x

Add the interest together to get the income for 1 year

.055x+  .15x+22500 - 0.18 x=25,000

Combine like terms

0.025x+22500=25000

Subtract 22500

.025x =2500

Divide by .025

x =100000  

short term notes is 100000

3*x = 300000 = government bonds

The rest is utility bonds 500000- 100000-300000 = 100000

We want how much more in government bond than utility bond

300000 -100000 = 200000
