Answer:
40
Step-by-step explanation:
15x3 = 45
45-5 =40
You use additive inverse to combine like terms that are on opposite sides of the equation.
ie.
3x + 1 = 6x -12
You use additive inverse to move -12 to the +1
What? Do you have a picture that reveals what you need help in?
1 yard ≈ 0.9144 m
Therefore,
10 yards = 10*0.9144 m = 9.144 m
13 yards = 13*0.9144 m = 11.8872 m
Area to be covered = 9.144*11.8872 = 108.697 m^2
Therefore, Samantha will require approximately 109 m^2 of carpet.
Well, if it was out of 50, it would be 76%.
So the answer might be 50 questions total, but maybe there was 49 questions total.
I would probably go with 50 questions total.
