Answer:
C) 5x=5
Step-by-step explanation:
Multiplying an equation by a number means multiplying all its terms by that number.
Multiplying equation one by 2,
2(2x+y=3)
4x+2y=6
Adding that to equation 2,
4x+2y=6
+ x-2y=-1
The result is 5x=5
Answer:
Step-by-step explanation:
33/7 = 4 5/7
4*7= 28
5 is left.
So it would be 5/7 plus the 4.
28/6 = 4 4/6
4 4/6 + 4 5/7=
4 27/42 + 4 30/42= 4 57/42
4 57/42= 4 15/42 or 4 5/14
The answer is B) 55.5 Do you need me to work it out for you?
It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.
