Answer:
52
Step-by-step explanation:
Alex earned 156 reward points for selling wrapping paper rolls.
Using the given equation
3r = 156
r = 156/3
r = 52
Alex sold 52 wrapping paper rolls
5x - y = 3 ------------ (1)
6x - y = 8 ------------ (2)
From (1):
5x - y = 3
y = 5x - 3 ------------ Sub into (2)
6x - (5x - 3) = 8
6x - 5x + 3 = 8
x + 3 = 8
x = 5 ------------------- Sub into (1)
5x - y = 3
5(5) - y = 3
25 - y = 3
y = 25 - 3
y = 22
---------------------------------
Ans: x = 5, y = 22
---------------------------------
Let the integers be x-2, x, x+2.
Given,
x -2 + x + x + 2 = 69
3x = 69
x = 23
Hence, the integers are 21, 23 and 25.
