If you would like to solve the equation 9/11 = x/22, you can calculate this using the following steps:

9/11 = x/22    /*22
x = 9/11 * 22

36/49 = 5/n find n. will mark for whoever answers
Crazy boy [7]

Answer:

  n = 245/36

Step-by-step explanation:

Usually, these are solved in 2 steps:

  1. eliminate fractions by multiplying by the LCM of the denominators
  2. divide by the coefficient of the variable.

Doing that, we have ...

  (49n)(36/49) = (49n)(5/n)

  36n = 49·5 = 245 . . . . . simplify

  n = 245/36 . . . . . divide by the coefficient of n

_____

Another way to do these is to rewrite the proportion with both sides inverted:

  49/36 = n/5

Now, all you need to do is multiply by 5.

  n = 5(49/36) = 245/36

__

Or, you can do both of the original steps at the same time:

  (49n/36)(36/49) = (49n/36)(5/n)

  n = (49·5)/36 = 245/36

MATH!!! 15 points ;)) find the volume of the composite figure
andrezito [222]

Answer:

(2*2*1.5*1/3)+(2*1.5*4)= 14

Step-by-step explanation:

To find the area of a pyramid, you use the equation of 1/3 *lwh. When we place the values in there, we get 2*2*1.5*1/3, which is equal to 2. Then we solve the bottom part. Since it is a rectangular prism, we use the equation of lwh. When we insert the values, we get 2*1.5*4, which is equal to 12. Now, we take these two values of 2 and 12 and we combine them, giving us our final answer of 14.
