The three angles must add to 180. So x=180-(50+90)= 40 degrees.

Answer: 40 degrees

Step-by-step explanation:

Since the rectangle is 90 degrees and we know that the line is 180 degrees if u add 90 and 50 it becomes 140. Now u subtract from 180 to get 40 hope that helps and is a correct answer :)

What your teacher wants is for you to isolate y in the given equation. In other words, get y all by itself. 

To do this, you'll do two basic steps:
Step 1) Subtract 2x from both sides
Step 2) Divide both sides by 3

Let's do that and we get...
2x+3y = 1470
2x+3y-2x = 1470-2x ... apply step 1
3y = 1470-2x
3y = -2x+1470
3y/3 = (-2x+1470)/3 ... apply step 2 
y = (-2x)/3 + 1470/3
y = (-2/3)x + 490

After isolating y, we get y = (-2/3)x + 490
To get this into function notation, we simply replace y with f(x) to get the final answer f(x) = (-2/3)x+490 which is the same as writing f(x) = -\frac{2}{3}x+490

This graph represents all of the ordered pairs (x,y) that make the original equation true. For example, the point (x,y) = (0,490) is on the line where x = 0 and y = 490. This point is when 0 sandwiches are sold and 490 wraps are sold yielding a profit of $1470. Another point on this line is (x,y) = (3,488). Now 3 sandwiches have been sold along with 488 wraps leading to the same profit of $1470. Any ordered pair point you pick on the line should lead you to the same profit.

An empty cup in the shape of a cylinder is being filled with water . The cup is filled at constant rate . The table below shows
KatRina [158]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. I'll help you to understand this problem, but I have to assume some things.

We know that the empty cup in the shape of a cylinder is being filled with water. Suppose the volume of this cylinder is:

V=450cm^3

Suppose that the cup is filled at a constant rate of s=50cm^3/s, so in 7 seconds the cup is filled the following amount:

V'=50\times 7=350cm^3

So this represents the following percentage:

\frac{V'}{V}\times100=\frac{350}{450}\times 100=77.78\%

Finally, after 7 seconds the cup is 77.78% filled
