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 adding 3.8 to both sides. 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! :)

a + b ≥ 30, b ≥ a + 10, the system of inequalities could represent the values of a and b

option A

Step-by-step explanation:

Here we have , The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is the greater integer, We need to find which system of inequalities could represent the values of a and b . Let's find out:

Let two numbers be a and b where b>a . Now ,
