First you have to find 1/3 of the marbles. That means in the twelve marvels she has, there are three even groups. Divide twelve by three and you get four. So if each group is four, it is simple from here on out. If she started out with twelve and she lost 1/3 of them(4) it would be 12-4. You know this because lost is another for for subtract. 12-4=8. She has 8 marbles left.
the slope is -6/5. This is because it goes down 6, and then to the right for 5. You can also use the slope formula to solve this.
Answer:
2. 4
Step-by-step explanation:
use the formula A=ab/2
a-leg 1
b-leg 2 (base)
since it is a right triangle the height would be 2 cm and the base would be the leg (4 cm)
plus into the equation- A= 2(4)/2
8/2=4
