Answer:
sali's speed was 18.75 km/h
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As, , so the speed of Jane will be:
Suppose, the speed of Sali is km/h
Sali caught up with Jane when they had both cycled 30 km.
So, the time required for Jane to cycle 30 km and the time required for Sali to cycle 30 km
Given that, Sali started to cycle 4 minutes or after Jane started to cycle. So, the equation will be.......
Answer:
Step-by-step explanation:
(12-3)/2 = 9/2
(-5-3)/2= -8/2= -4
(9/2, -4)
Knowing the ratio for dogs to cats is 10:9
To get to 50 dogs they multiplied 10x5
So multiply 9x5 as well to get the number of cats
Cats = 45

This is simple. :)
All you have to do is plug in each of the coordinates.
So, for the first one, you would take the first option (-2,-9). The equation would look like this: -9=3(-2). -2*3 doesn't equal -9, so you move on to the other options, testing them out.
The second question is the same. For example, you take (2,14), plug it into the equation to make it look like this: 14=-5(2)+4
-5*2=-10
-10+4=-6
So the first option is not correct.
I hope this helps
