Answer:

3

Step-by-step explanation:

Let's go through this together.

Step 1) Rearrange Terms (Optional)

9 + x = 12

x + 9 =12

Step 2) Subtract 9 from both sides of the equation

x + 9 = 12

   -9    -9

Step 3) Simplify

If we subtract 9 on both sides, we end up with:

x + 0 = 3

Since 0 no longer has any part in the equation, we can conclude that:

x = 3

wariber [46]

Answer:

the other sides are 9 and 12

Step-by-step explanation:

use the Pythagorean theorem.

a^{2} +b^{2} =c^{2}

you know that c^2 is 225 because 15*15=225

a^{2} +b^{2} =225

(from here on I just plugged numbers in)

3:4=9:12

9^{2} +12^{2} =225

81+144=225

225=225

Yaaaaay!

Ms. Wall will roll two number cubes. What is
bonufazy [111]
Probability of rolling a sum of 9 or a sum that is even from two number cubes is
11/18
Explanation:
When a dice is rolled there are different ways in which
9. can be obtained, which are (3,6) or (4,5) or (5,4) or (6,3). 4 options. As in all there are
6⋅6=36 options, probability is 4/36 or 1/9.

For getting an even number as sum, we can have (1,1) or (1.3) or (1,5) or (2,2) or (2,4) or (2,6) or (3,1) or (3,3) or (3,5) or (4,2) or (4,4) or (4,6) or (5,1) or (5,3) or (5,5) or (6,2) or (6,4) or (6,6) 18 options, probability is 18/36 or 1/2.

Note that the two events (getting 9 or even sum) are mutually exclusive, the probabilities can be just added i.e. combined probability is
1/9+1/2=2+9/18i.e. 11/18
