13*d = 1 mod 60 PLEASE WITH STEPS I WILL GIVE BRAINLIST​

Step-by-step explanation:

Modulo can be read as:

For , what is the remainder when is divide by ?

Therefore, we're looking for a number that when divided by 60 returns a remainder of 1.

Compare multiples of 13 and 60 to find a pair where the multiple of 13 is exactly 1 greater than the multiple of 60.

After some digging, we find that

Therefore, we can substitute with :

Since there are clearly more than one number that when divided by 60 returns a remainder of 1, any valid answer 60 will also be a valid answer. Therefore, , for all real numbers .

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
