Step-by-step explanation:
i dont know how to explain, and again sorry for questions 4-9
Well, what you would do is 60% of 150, you'd change the if to a multiplication sign. 60/100x150/1. then follow the photo. I THINK!!
Since 58 for vanilla and 28 for chocolate
The ratio would be 28:58
You can simplify it even further
to 14:29
Factor out the 4 in both equations
8a^2-20^2=(2^2 times a^2 times 2)-(2^2 times 5)
therefor it is also equal to
(2a)^2 times 2-(2^2 times 5)
we can force it into a difference of 2 perfect squares which is a^2-b^2=(a-b)(a+b)
(2a√2)^2-(2√5)^2=((2a√2)-(2√5))((2a√2)+(2√5))
Express 0.31 as a fraction and express 0.2 as a fraction
