Answer:
(x, y) = (8, 2)
Step-by-step explanation:
The relevant equations are ...
3x -y = 22
x +2y = 12
__
We can eliminate y by adding twice the first equation to the second.
2(3x -y) +(x +2y) = 2(22) +(12)
7x = 56
x = 8
Substituting into the first equation gives ...
3(8) -y = 22
y = 24 -22 = 2
The first number is 8; the second number is 2.
Answer:
120 days
Step-by-step explanation:
Tacos are served every 60 days.
Cheeseburgers are served every 8 days.
Since, both Cheeseburgers and Tacos are served today, the next day on which both will be served is gotten by finding the Lowest Common Multiple of 60 and 8.
To find the LCM,
First, we express the numbers as a product of their prime factors.
60= 2X2X3X5=2²X3X5
8=2X2X2=2³
Next, we take each of the term with the highest power and multiply.
L.C.M = 2³X3X5=120
After 120 days, Cheeseburgers and Tacos will be served on the same day.
