3) a^2+b^2=c^2
10^2+b^2=26^2
100+b^2=676
100-100+b^2=676-100
b^2=576
√b^2=√576
b=24
The rest are in the picture.

Answer:
Kayla sold more lemonade.
Step-by-step explanation
All you do to solve this problem is subtract 23 from 114.
12+.60+ 12.60
12.60*20%
12.60*.20= 2.52
Tip should be around $2.52
Hope this helped :)
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:

Add 3x to both sides:

Add 6 to both sides:

Which is of course equivalent to

Divide both sides by 9

So, every number smaller than 2 is part of the solution of this inequality.
