There's no need for a system of linear equations if you were to solve a real life problem like this. In calculus, they don't give a rat about HOW you get your answer to an easy algebra 1 equation, as long as you used one of the correct methods and got the right answer.
Best of luck my friend. :)
Let's just start with x=20 and then do some algebra to it to make it all complicated
x = 20
2 * x = 2 * 20
2x = 40
2x - 13 = 40 - 13
2x - 13 = 27
Answer:
(x - 3)^2 + (y + 2)^2 = 2^2.
Answer:
Step-by-step explanation:
First find difference between the divisors and remainders.
Here, the difference between the divisors and remainders is equal.
So, the required number is equal to LCM of
LCM of
Required Number
1/4 pounds. Each pound is 4$ so each dollar would equal a forth of a pound.
