Answer:

14

Step-by-step explanation:

To get the mean, you have to add all the numbers together, and then divide them by how many numbers there are. Here, i'll show you.

There are 6 numbers, including Y, which we need to find out.

The Equation:  \frac{4+6+9+Y+16+19}{6} = 13

  • We can simplify this equation into, \frac{54 + Y}{6} = 13

To find Y\\, we can do the inverse, and multiply 13 by 6.

(The 6 on the left side of the equation is then cancelled out)

  • \frac{54+Y}{6} = 13  becomes  54 +Y =13 × 6\\
  • 13 × 6 = 78 so then 54 + Y = 78

For this final equation to be true, Y would have to equal 14.

<em>Hope the rest of your math goes well :)</em>

Answer:-12 x 12 =- 144.

What you do is multiply regularly then add the negative sign, but if your multiplying  2 negatives it’s a positive answer. I cant help with the Fractions caz I’m not good at them lol .
