Answer:
He has 60 paper clips before giving some away.
Step-by-step explanation:
Before : 5x : 3x
After: 5x - 12 = 3x + 12
5x - 12 = 3x + 12
First, we need to take away the smallest value of x from the largest.
-3x
2x - 12 = 12
Then, we need to add +12 to get rid of -12 on the lefthand side.
2x = 24
Divide by 2 to get x on its own.
x = 12
Bert had 5x so we need to multiply x (what we found as 12) by 5. 12 x 5 = 60. Bert had 60 paper clips before he gave some away.
We can prove this answer as correct, too.
5 x 12 = 60
3 x 12 = 36
60 - 12 = 36 + 12
48 = 48
Hope this helps, have a good day. :D

Answer:
10
Step-by-step explanation:
The given is a special right triangle with angle measures as follows:
45-45-90
The side lengths for this special right triangle are represented as follows:
a (the side length that sees angle measure 45)
a (the side length that sees angle measure 90)
İn the image we can see that one of the side length that sees angle measure 45 is 10
so c, the side length that sees angle measure 90 (hypotenuse),
is equal to
10
