someone have at least three hats , all of his hats are orange excpet for two , all of his hats are brown expect for two and all his hats are blue expect for two how many hats does he have

3 hats

Step-by-step explanation:

I wanted to solve the question using mathematical approach, then I paused and realised, it was more of a logical question instead.

He has at least 3 hats, meaning it could be 4, 5 or any amount.

We're then told all of his hats are orange except for 2. Let's not mistake this statement to mean, he has 2 orange hats. The statement is rather saying, he has 2 non orange hats.

The same analogy goes for brown and that of blue also. Which brings me back to the question, he has at least 3 hats. What is he has just 3 hats?

This means that,

all his hats(3), except 2 are orange. 3 - 2 = 1. Meaning he has 1 orange hat.

all his hats(3) except 2 are brown. 3 - 2 = 1. Meaning he has 1 brown hat.

all his hats(3) except 2 are blue. 3 - 2 = 1. Meaning he has 1 blue hat.

In conclusion, 1 blue + 1 brown + 1 orange = 3 hats

what?

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
