3·(-5) =
This equation is the same way as writing it like this:
3(-5)=
Now we can use the distributive property.
3 times -5 equals -15

Place these numbers in order from greatest to least. 19/5, 1.62, –14/3, –0.5​

Answer:

See below:

Step-by-step explanation:

Hello my name is Galaxy and I'll be helping you today. I hope you are having a nice day!

Simplification

To figure out how we can order them, we can first simplify the problems so that we can easily determine its place. We can put the fractions into decimal form so that they are are in one form and will be easy for us to comprehend.

\frac{19}{5}=3\frac{4}{5}=3.80

We know that \frac{1}{5} is equal to 0.20 because we know that 1.00 will be equal to 100 in this case and we can divide that by five to get 20 which will be divided back to get to 0.20.

As I've explained how I've simplified the first one, simplifying the others should be a quite similar process, feel free to comment below if you need any assistance with this.

\frac{19}{5}=3.80\\1.62=1.62\\\frac{-14}{3}=-4.6667\\  -0.5=-0.5

(Everything simplified to decimal form.)

We can now proceed to ordering them.

Ordering

Ordering decimals doesn't have to be as hard as it looks, we know that as per the number line a number that is more negative (e.g. -37) will be less than (e.g. -5) as it is closer to the number 0.

Now that we know how to order the negative numbers, we can order them into order, and for ordering the positive numbers, we should already know how to do that.

So, now, in order from Greatest to Least. We can order them by what I said above.

3.80>1.62>-0.5>-4.666

We can convert the numbers back into their original form by looking at how we converted them in the Simplification section.

Final Answer

After converting them into a way that we can comprehend, we get our final answer in terms of greatest to least as:

\frac{19}{5}>1.62>-0.5>\frac{-14}{3}

Cheers!

Draw a model to represent the problem 1/2 divided by 2/8
Vlad [161]
The answer is 2 because 2/8+ 1/4 and 1/4 goes into 1/2 twice because 1/4 times 2 equals 2/4 and 2/4= 1/2.

I need to find each angle. Please help!!
Vlada [557]
Hello!

The interior angles of every triangle add to equal 180 degrees. With that, you can add all angle expressions and set them to equal 180 to find x:

180 = 2x + 50 + x + 46 + 3x
180 = 6x + 96
84 = 6x
14 = x

Now, substitute 14 for x in each expression to find the value of each angle:

2x + 50  =>  2(14) + 50  =>  28 + 50  =>  78
x + 46  =>  14 + 46  =>  60
3x  =>  3(14)  =>  42

Let's check our work:

180 ? 78 + 60 + 42
180 = 180  <--True

Angle A = 42 degrees
Angle B = 78 degrees
Angle C = 60 degrees

Hope this helps!
