If you use the equation for Rachel it would be
y=3x and for oliver it would be y=2x+5
Add the two speeds together, then divide the two, this gives the average speed. Hope this was helpful!
X is the number:
Therefore, the equation is:
8(x-2)=3(x+3)
8x-16=3x+9
8x-3x=9+16
5x=25
x=25/5
x=5
Answer: the equation is: 8(x-2)=3(x+3), and the number is: 5
It is not triangle because the one side of triangle should be smaller than the other two sides
Let's check
6+11=17
17<19
Or
11+19=31
9<31
Need more information. Is this a triangle? Can you attach a picture?
