Lets x = Mary's age
Emily is there years older than twice her sister Mary's age = 2x + 3
Sum of both is less than 30:
x + 2x + 3 < 30
Solve for x
3x + 3 < 30
3x < 27
x < 9
Mary's age = 9
Inequality represents Mary's possible age:
0 < x < 9
Answer is the second one
0 < x < 9

Answer:
Step-by-step explanation:
In this question, we're trying to find how many circles are there and represent it as a fraction.
We know that he drew:
- 3 triangles
- 4 rectangles
- 7 arrows
- Set of 20 shapes
We need to find how many circles are there.
3 tiangles + 4 rectangles + 7 arrows = 14 shapes
We know that there is suppose to be 20 shapes, this means that the remaining amount would be circles (6 circles)
We now know that there are 6 circles and 20 shapes in total.
This means that the fraction that would represent circles is 6/20
