The answer is: X=9 first step is to distribute 2 into 4x and -10 then move the 8x over behind the 3x, then combine 8x and 3x together to get -5x=-20-25 combine -20 and -25 to get -45 then divide -45 by -5 to get x=9

Answer:

x=9

Step-by-step explanation:

3x + 25 = 2(4x – 10)

3x + 25 = 8x-20

3x-8x=-20-25

-5x=-45

5x=45

x=9

Find the value of x and y

Inessa [10]

Answer: D. x=9√3; y=18

Step-by-step explanation:

This is a 30-60-90 special triangle, where we can use the rules to find the value of x and y. (For specific explanation, please look at the attachment below)

-----------------------------------------------------------------------------------------------------

<u>X value</u>

- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.

- Using the rules, the shortest side is x, then the second short side is x√3

- Substitute value in= x√3=(9)√3=9√3

Y value

- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.

- Using the rules, the shortest side is x, then the longest side is 2x

- Substitute value in= 2x=2(9)=18

Hope this helps!! :)

Answer:

The slope is $0.35/min and it gives the cost per minute of the phone used.

Step-by-step explanation:

We can model this situation with a linear equation of the form

$y =mx+b$

where $y$ is monthly cost, $x$ is the number of minutes, $b$ is the flat monthly fee, and $m$ is the slope of the equation, or in our case, the amount of money charged per minute.
