Answer:
2
Step-by-step explanation:
this is because the inequality sign says greater than OR equal too, this would make the line solid, and since it's greater, all the values above that line would be included in the inequality
1. C -9
2. B 7.5
3. A -4
4. C 65
Answer: A = 20
How to Solve:
Just by looking at this problem I can tell that the denominators (9 an 45) are factors of 9. So the second equation is multiplied by 5 from the first equation.
4/9 x 5
4 x 5 = 20
— -—
9 x 5 = 45
So A would be 20.
Another way to solve this would be by multiplying the 1st equations numerator with the second equations denominator:
4 x 45 = 180
Then divide 180 with the 1st equation’s denominator.
180 / 9 = 20
A = 20

Answer:6km
Step-by-step explanation:
Given
when Alice finishes the race Becky is 8km From finishing line
and caitlin 12 km from finishing line.
Suppose t is the time require by Alice to finish the race
and
be the velocity of alice ,becky and caitlin
thus 
thus 
say t' is time required by beckey to complete 8 km thus

therefore for Caitlin

Thus caitlin will cover a distance of 6 km in t' time and 6 km away from finishing.
