Step-by-step explanation:
Answer:
9
Step-by-step explanation:
percentages are reversable. like instead of 18% of 50 you could reverse it and say what is 50% of 18. which is 9.
I believe this just uses the Pythagorean Theorem. A^2+B^2=C^2. So:
15^2+B^2=25^2. Simplified this is,
225+B^2=625
625-225=400
B^2=400
√ B=<span>√ 400
</span>B=20
Remember you can do anything to an equation as long as you do it to both sides
4x-5=4x+10
minus 4x both sides
-5=10
false
no solution
The answer is 77 since you would use PEMDAS and multiply 12 * 4 first to receive 48 which then adding a 29 to the 48 resulting in 77
