7/3x+1/3x=3x+6/3+5/3x
8/3x-5/3x=3x+6/3
3/3x=3x+6/3
x=3x+6/3
x-3x=6/3
-2x=2
-x=2/2
-x=1
x=-1

4) Solve for x: 2x=8.
MatroZZZ [7]
4) x=4  -> divide by 2
5) y=9  -> add 2
6) z=2 -> multiply 2 times 1
7) a=10   -> add 7 then divide by 3
8) b=3  -> distributive property, add 1 to other side, and then divide by 8
9) c= -d +4   -> subtract +d+1 and put on other side to solve
10) m= 10/p+2  -> distrubutive property, subtract 2m on both sides to solve

mix 1 part of shampoo to six parts of warmwater.How much water do you need to mix with 200 ml of shampoo?
borishaifa [10]
For every one part, or in this case 200 ml of shampoo, there are three parts water. This means that there is 6 times more water than shampoo. 200 * 6 = 1200 ml of water

Rewrite f(x) = sin(x) if The function of scratch vertically by a factor of 5
adoni [48]

let's not scratch sin(x), she may not like it anyway, but let's do some stretching by checking this template


\bf ~~~~~~~~~~~~\textit{function transformations} \\\\\\ f(x)=Asin(Bx+C)+D \\\\ f(x)=Acos(Bx+C)+D\\\\ f(x)=Atan(Bx+C)+D \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \bullet \textit{ stretches or shrinks}\\ ~~~~~~\textit{horizontally by amplitude } A\cdot B\\\\ \bullet \textit{ flips it upside-down if }A\textit{ is negative}\\ ~~~~~~\textit{reflection over the x-axis} \\\\ \bullet \textit{ flips it sideways if }B\textit{ is negative}\\ ~~~~~~\textit{reflection over the y-axis}

\bf \bullet \textit{ horizontal shift by }\frac{C}{B}\\ ~~~~~~if\ \frac{C}{B}\textit{ is negative, to the right}\\\\ ~~~~~~if\ \frac{C}{B}\textit{ is positive, to the left}\\\\ \bullet \textit{vertical shift by }D\\ ~~~~~~if\ D\textit{ is negative, downwards}\\\\ ~~~~~~if\ D\textit{ is positive, upwards}\\\\ \bullet \textit{function period or frequency}\\ ~~~~~~\frac{2\pi }{B}\ for\ cos(\theta),\ sin(\theta),\ sec(\theta),\ csc(\theta)\\\\ ~~~~~~\frac{\pi }{B}\ for\ tan(\theta),\ cot(\theta)


A = 1/5, so then .......... \bf g(x)=\cfrac{1}{5}sin(x)

Can someone please answer. There is one problem. There's a picture. Thank you!
laila [671]
The answer is D, or 168. 
The cheese can be any one out of 3 = 3 choices.  For each of those . . .
The first topping can be any one of 8.  For each of those . . .
The second topping can be any one of the remaining 7 . For each of those . . .
The third topping can be any one of the remaining 6 .

Total number of ways to assemble a pizza = (3 x 8 x 7 x 6) =  1,008 ways.

<span>BUT . . . </span>

You could choose the SAME 3 toppings in (3 x 2) = 6 different ways, and
nobody could tell the difference once they were selected.  All 6 different
ways would result in the same pizza.

So, out of the 1,008 total different ways there are of choosing ingredients,
<span>there are only ( 1,008 / 6 ) = </span>168<span> different and distinct pizzas.</span>
