NATSUNO is correct. The answer is 16.

Basically, if the line is straight, it will equal 180.

So your equation should be:
18x - 215 + 5x + 27 = 180 (it could also be (5x + 27 + 18x - 215 = 180).

Once you got that down, add your like terms: 18x + 5x and -215 + 27 You should get 23x and -188.

You want to solve for x, so get x alone by adding -188 to 180.
It looks like this: 23x - 188 = 180
+188 +188

Now you’re left with: 23x = 368. Divide 368 by 23x, and x = 16.

Um not fully confident which is funny because imma freshman but i believe you combined all the like terms to get “180 = 23x - 188” and it equals 180 in the end because it’s a straight line so anyways once you solve the problem you should get 16 i believe and if you’re confused just feel free to ask me and i hope i wasn’t too late to answer it

How many times does 5 go into 100
Rasek [7]
<span>I believe in this item, we are asked to determine how many 5's should be added together in order to form 100. This is calculated by dividing 100 by 5. The answer by completing the operation would be equal to 20. Hence, the answer is 20. </span>

(09.01) A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsiu
lukranit [14]

Answer:

x-intercept:

A line that crosses the graph at x-axis.

i.e substitute y = 0 and solve for x.

As per the statement:

A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water

Given the graph:

y = -2x^2+20x+400

Substitute y = 0  we have;

-2x^2+20x+400 = 0

⇒-2(x^2-10x-200) = 0

⇒x^2-10x-200 =0

⇒x^2-20x+10x-200 =0

⇒x(x-20)+10(x-20)=0

⇒(x-20)(x+10)=0

By zero product property we have;

x-20 =0 and x+10 = 0

⇒x = 20 and x = -10

Therefore,  the x-intercept represents the water has no larvae at −10 degrees Celsius and 20 degrees Celsius.
