Set up proportions
8/28=5/21
8*21=168
5*28=140
so no, they are not equivalent
2(x+y)=24
2x=y
Use substitution. If y=2x, than we can substitute 2x for it in the other equation, because x and y equal the same things in both equations.
So using that we get 2(x+2x)=24
SIMPLIFY
2(3x)=24
DISTRIBUTE
6x=24.
DIVIDE: x=4.
If we substitute x into the original equations we get x=4 and y=8. Those are your two numbers.
Have a nice day! :)
Answer:
theta = 48.190
Step-by-step explanation:
Let, snake catches the mouse in t hours. Till then mouse is travelling from
( t + 1.5 ) hours.
Distance, travelled by mouse in t hours is,
.
To catch the mouse snake had to travel the same distance d in t hours.
So,
![200t = 100( t + 1.5 )\\\\2t = t + 1.5\\\\t = 1.5 \ hours](https://tex.z-dn.net/?f=200t%20%3D%20100%28%20%20t%20%2B%201.5%20%29%5C%5C%5C%5C2t%20%3D%20t%20%2B%201.5%5C%5C%5C%5Ct%20%3D%201.5%20%5C%20hours)
Therefore, snake will catch mouse in 1.5 hours.
