3/4 W + 8 = 1/3 w – 7
Montano1993 [528]

Answer:

<h2>W = -36</h2>

Step-by-step explanation:

\dfrac{3}{4}W+8=\dfrac{1}{3}W-7\qquad\text{subtract 8 from both sides}\\\\\dfrac{3}{4}W+8-8=\dfrac{1}{3}W-7-8\\\\\dfrac{3}{4}W=\dfrac{1}{3}W-15\qquad\text{multiply both sides by}\ LCM(4,\ 3)=12\\\\12\!\!\!\!\!\diagup^3\cdot\dfrac{3}{4\!\!\!\!\diagup_1}W=12\!\!\!\!\!\diagup^4\cdot\dfrac{1}{3\!\!\!\!\diagup_1}W-(12)(15)\\\\(3)(3W)=(4)(1W)-180\\\\9W=4W-180\qquad\text{subtract}\ 4W\ \text{from both sides}\\\\9W-4W=4W-4W-180\\\\5W=-180\qquad\text{divide both sides by 5}\\\\\dfrac{5W}{5}=\dfrac{-180}{5}\\\\W=-36

What’s 1/50 rounded to the nearest 100
blagie [28]

Answer:

*Under the assumption you mean "What's 1.50 rounded to the nearest 100th"*

1.50<====

Step-by-step explanation:

Looks like a trick question. The first number after the decimal is a tenth, the next one a hundredth. There is no thousandth to round up the hundredth and so the number is already rounded.

8^x+3=16^x−1<br> solve the exponential equation ...?
Juli2301 [7.4K]
Let us write down the equation clearly and in a proper manner. This will help in solving the equation very easily.

8^(x + 3) = 16^(x - 1)
(2^3)^(x + 3) = (2^4)^(x - 1)
(2)^3(x + 3) = (2)^4(x - 1)
Then
3(x + 3) = 4(x - 1)
3x + 9 = 4x - 4
4x - 3x = 9 + 4
x = 13

I hope the procedure is clear enough for you to understand. I also hope that this is the answer that has actually come to your desired help.
