The linear combination method is the same as the elimination method. Let's multiply the second equation by -2 so the x terms cancel each other out. When we do that we get a system of
and
. The x-terms cancel each other out giving us
and y = -3. Now sub -3 into one of the equations to solve for x. x+2(-3)=-4, and x - 6 = -4. x = 2. So the solution for our system is (2, -3)
Answer:
Step-by-step explanation:
The unit rate is pages per minute, so divide the pages by the minutes: (5/8)/(2/3) = (5/8)·(3/2) = 15/16 pages per minute
Answer:
A
Step-by-step explanation:
1/4
The two answers would 4/12 and 9/12. This is because one third of 12 is 3 and three fourths of 12 is 9.
