Me, these 2 questions are crazing me out!

#1: -25/52

#2: 16x-8y

Step-by-step explanation:

For the first one *the one that you're simplifying*, you need to turn 2 3/5 into an improper fraction. 2 3/5 will become 13/5.

(-5/4)/(13/5)=(-5/4)*(13/5)= -25/52

For the second one *the one that's the perimeter of the square*, you already know that all of a square's sides are the same length. That means, if one of the sides is (4x-2y), then all of them will be (4x-2y). You can either add them like this: (4x-2y)+(4x-2y)+(4x-2y)+(4x-2y), or just multiply it by 4, which will be:

4(4x-2y)

16x-8y

I hope this helped, even just a little bit! :)

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest
