To solve for R you use PEMDAS
You would divide 121 by 8.
121 / 8 = 15.125 So she did about 15 sit ups in a minute. Hope this helps!
M=-1/2 because you do y1-y2 over x1-x2 and end up with 2/-4 but simplified is -1/2
Answer:
A system of two linear equations can have one solution, an infinite number of solutions, or no solution. Systems of equations can be classified by the number of solutions. If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent .
