Answer:

x = 16.5

Step-by-step explanation:

In this equation, we're trying to figure out the value of x, or what it's equivalent to in this particular situation. Let's look at what we have right now:

12.7 = x - 3.8

How can we get x by itself? Well, the thing that immediately comes to my mind is <em>adding 3.8 to both sides</em>. This will isolate x and help is figure out what it's equal to. So, we start out with:

12.7 = x - 3.8

...and then we add 3.8 to both sides to get:

16.5 = x

And that's the value of x. We can check our answer by replacing x with 16.5 and seeing if both sides of the equation are equivalent:

12.7 = 16.5 - 3.8?

12.7 = 12.7

So, we're correct. If you need any more help, let me know! :)

What is the distance between (10, 6) and (-2, -3)

Helga [31]

Answer:

15 units.

Step-by-step explanation:

The distance between the points (x1, y1) and (x2, y2) is

√(x1-y1)^2 + (y1-y2)^2))

So here it is:

√(10- -2)^2 + (6- -3)^2)

= √(144+81)

= √225

= 15.

Need help with some inverse trigonometric expressions, rounded to the nearest degree.

rjkz [21]

A Google or Bing search box can be your friend, if you don't have a calculator with inverse trig functions. Most calculators that have trig functions also have the inverse functions, usually after a 2nd or "shift" key. Often, there is a mode setting for degrees or radians.

arcsin(0.33) ≈ 19°
arccos(0.47) ≈ 62°
arctan(1.21) ≈ 50°
arcsin(0.82) ≈ 55°

Imagine there are 5 cards. They are colored red, yellow, green, white, and black. You mix up the cards and select one of them wi

iragen [17]

Step-by-step explanation:

step one:

given that the sample space is

red, yellow, green, white, and black. i.e (1+1+1+1+1)= 5

the sample size is 5

the probability of picking a colored card at random is

Pr(a colored card)= 1/5

step two:

without replacement, after the first event, the sample size is now 4

then the probability of picking a colored card at random is

Pr(a colored card)= 1/4
