Julie weighs 35 lbs, Ted weighs 70 lbs, and Mike weighs 105 lbs
Julie's weight = x
Ted's weight = 2x
Mike's weight = 3x
3x + 2x + x = 6x
6x = 210
x = 35
3(35) + 2(35) + 1(35) = 210
105 + 70 + 35 = 210
I think you should write the equation to find perimeter such as P = 2(L + W). So the expression is 2[2(x+y) + 3(x - y)]
Simplified as 2[(2x + 2y + 3x - 3y)]
2(5x - 1y) combined like terms
10x - 2y is the expression for the perimeter of the rectangle
Step-by-step explanation:
here's the answer to your question
Answer:
C
Step-by-step explanation:
In the attached file
2/3=8/12. 10 and 8/12
3/4=9/12. 8 and 9/12
128/12-105/12=23
23/12=1 11/12
No you are incorrect. It is not 2 and 11/12, but 1 and 11/12.
