What is the solution to the linear equation?2/5 + p = 4/5 + 3/5p​

Mathematics

Answer:

<h2>p = 1</h2>

Step-by-step explanation:

\frac{2}{5}  + p =  \frac{4}{5}  +  \frac{3}{5} p

Multiply through by the LCM

The LCM for the equation is 5

That's

5 \times  \frac{2}{5}  + 5p = 5 \times  \frac{4}{5}  +  \frac{3}{5}p  \times 5

We have

2 + 5p = 4 + 3p

Group like terms

5p - 3p = 4 - 2

2p = 2

Divide both sides by 2

We have the final answer as

<h3>p = 1</h3>

Hope this helps you

Answer:

72

Step-by-step explanation:

The LCM is when you find the lowest factor that 2 or more numbers share.

For 8 and 9,you would just need to keep multiplying each other until you find the same numbers. It would look something like this.

8,16,24,32,40,48,56,64,72..... etc.

9,18,27,36,45,54,63,72,81..... etc.

You can see how they both have the same factor (72), and since that is the lowest factor (which means I can find a lower factor then 72) then your LCM of 8 and 9 should be 72 :)

How many solutions does the system have?
serious [3.7K]
The system has two solutions.

You can tell because the second equation is a quadratic and the first is a line, so the line passes through the quadratic twice.

8/9 divided by -1 4/15
Marina86 [1]

You can use the keep it, change it, and flip it method. Keep the 8/9. Change the division to multiplication. Flip -14/15 (it becomes -15/14). So, your answer would become 20/21.
