Answer:
19/117
Step-by-step explanation:
Because the dice did land on 5, 19 times out of 117
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
Answer:
Zhang: 17, Robert: 22
Step-by-step explanation:
Robert's age would be z+5, 2×z+5=39, z=17 So Zhang's age would be 17, and Robert's would be 22
Yes; to figure this out just plug the x,y values into the equation and make sure they come out true
