The sum of three numbers is 83. The second number is 5 less than the first. The third number is 2 times the first. what are the
coldgirl [10]

Answer:

22, 17, and 44.

Step-by-step explanation:

So what you do is you will have three equations that we will put together.

1. x. The first number is x because they don't give us anything about it.

2. x-5. It says that the second number is 5 less than the first number.

3. 2x. It says that the third number is 2 times the first number.

<em>x+x-5+2x=83. </em>

<em>4x-5=83.</em>

<em>4x=88.</em>

<em>x=22. </em>

That is the first number. To find the second and third, you will plug 22 into the x.

2. 22-5=17.

3. 2(22)=44.

22, 17, 44 are your answers.

Solve the following inequality
Contact [7]

Answer:

6 < u < 8

Step-by-step explanation:

10 > 5u/4 > 15/2

To solve this, we need to isolate the variable u

10(4) > 5u/4(4) > 15/2(4)

40 > 5u > 30

40/5 > 5u/5 > 30/5

8 > u > 6

It probably wants you to write it in order so,

6 < u < 8

Your welcome, and if you have any questions, feel free to comment! :D
