Answer:

8/5 or 3.6

Step-by-step explanation:

1.03x + 3.97x = 5x

So in this equation, it would be:

5x - 5 = 13

Subtract 5 from both side:

5x + 5 - 5 = 13 + 5

5x + 0 = 18

5x = 18

Divide both side by 5

5x/5 = 18/5

1x = 18/5

x = 18/5 or 3.6

Hope this help you :3

Answer:

X = \frac{18}{5}, or X = 3.6

Step-by-step explanation:

For this problem we must isolate x

1.03x+3.97x-5=13 | Add 5 to both sides

1.03x+3.97x=18 | Add the x's

5x=18 | Now divide both sides by 5

x=\frac{18}{5}, x=3.6

Which could be the entire interval over which the function,
Marrrta [24]

Answer:

(-2, 1)

Step-by-step explanation:

Hi Juliadayx! How are you?

Well, maybe you already heard about the domain and the range of a function.  

The domain is the set of values that the independent variable can take (usually referred to as the letter "x"), while the range is the set of values that the dependent variable takes, which is called f(x) or function of x.

In this case, the exercise asks you to evaluate for which values of “x” (right column of the table), the function “f(x)” takes positive values (left column of the table), the positive values also include zero. And in this case you can see that the function f(x) is only positive for the values of "x": -2, -1, 0 and 1. Therefore, the answer is the entire interval (-2, 1).

I hope I've been helpful!

Regards!

Can someone explain me to me how to solve this
matrenka [14]

Answer:

4/10 or simplified to 2/5

Step-by-step explanation:

when dividing fractions by a whole number, you want to imagine the whole number as a fraction. which would be 2/1. So you want to use the reciprocal of 2/1 which is 1/2. Then you multiple 4/5 by 1/2 which is 4/10 or simplified to 2/5 hope this helps :)

what is the value of the largest 2 digit whole number whose digits have a product of 6?---please explain!!
loris [4]
~Hello There!~

Product means they multiply to make 6
Think of numbers that multiply to make six:
1 x 6
6 x 1
3 x 2
2 x 3
The largest out of those is clearly 6 x 1 which makes 61

Hope This Helps You!
Good Luck :)
