Arturo's family hires 3 painters. Each painter charges $50 per hour. Arturo's family represents the charge for x hours of painting in different ways. Check all that apply to this situation A. 150x
B. 50x+50x+50x
C. 50x
D. 150

please don’t guess random answers, thank you. 20 points for answering!

D

Step-by-step explanation:

So if Arturo's family hires 3 painters for $50 an hour each, how much do they spend?

X= Charge for number of number of hours

Now let's say that each of the painters worked only one hour each.

That would be take a long time to add up so you multiply.

$50 x 3

In other words it's $50 + $50 + $50.

$50 x 3 = $150

Now X stands for the amount of money paid to each artist. In this case, X= $50. So we already figured out X. X is $50. It is a mistake to add the X at the end of the answer because X is already there in a numerical form. So the answer is D, $150.

Explanation:

One painter charges $50 an hour. If they work for x hours, then they charge a total of 50x dollars.

For instance, let's say the painter works for x = 7 hours. This means s/he charges 50*x = 50*7 = 350 dollars overall.

That's for one painter. If we involve 3 painters, then the total bill comes to 50x+50x+50x = 150x dollars

We could also say 3*50x = 150x, since 3*(cost of one painter) = total cost for three painters.

This is why choices A and B are the two answers.

Choice C would be the answer if you only hired one painter. But instead, you hired three of them, so we can rule out choice C.

Choice D only works if x = 1 is plugged into 150x to get 150*x = 150*1 = 150. However, you don't want to limit yourself to this x value only. It's better to stick with 150x instead to be more general. That way you can find the cost for say x = 2 hours which is 150*x = 150*2 = 300 dollars. I'll let you try other x values.

the solution is 12x-6y

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
