x – y = 30, when y = 15

Then plug in the value

x - 15 = 30

Add 15 to both sides

x -15 + 15 = 30 + 15

Simplify:

x = 45

X-y=30 <=> x-15=30 =>x=30+15 => x=45

How many ways can 100 be written as the sum of distinct integers from the set {1, 2,..., 15}?

konstantin123 [22]

Answer:

48 ways

Step-by-step explanation:

Let me take a guess

S₁_₁₅ = (1+15)*7 + 8 = 120

There are 48 combinations of distinct digits from 1 to 15 to make 20

120-20=100

So every 20 has a corresponding 100

I wish I got it right, otherwise report it.
