Hello!

Let's write this as an equation below.

3(x-2)=-15

First we undo the parentheses.

3x-6=-15

We add 6 to both sides.

3x= -9

We divide both sides by 3.

x= -3

Therefore, our number is -3.

I hope this helps!

2. In the diagram below, set I represents rational numbers, set II represents integers, and set III represents whole numbers. Sh
MrRa [10]

The information about the rational numbers and integers shows that the correct option is C.

<h3>How to explain the information?</h3>

It should be noted that rational numbers are numbers where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.

Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.

Of the four answer choices, only choice C is correct.

Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.

Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.

Therefore, the correct option is C.

HELP PLEASE<br> A. 51.4<br> B. 50.0<br> C. 31.0<br> D. 39.5<br> E. None
Liono4ka [1.6K]
First, in order to find the length of side w, you must first find the angle W. 
A triangle must be 180 degrees in total. 93 + 37 makes the triangle only have 130 at the moment. 
180 - 130 = 50
So angle W is 50 degrees
Now using this, we can use law of sines.
\frac{w}{sin50} =  \frac{31}{sin37}
Now multiply sin 50 on both sides. It can be written like so:
\frac{31sin50}{sin37}
Now plug this in a calculator. 
Answer is 39.5
