Answer:
imagine the upper triangle as the same as the lower one, but rotated by 180° around the corner point they share, and resized.
the base of the smaller triangle is resized by a factor of 3/4.5, or reduced: 1/1.5
we just take the length from the hypotenuse of the bigger triangle and resize it to, either by multiplying with 1/1.5 or by dividing by 1.5
personally, I find the latter easier.
x = 7.5/1.5 = 5
Answer:
4. 2.4
5. 
6. IV
Step-by-step explanation:
4. 3 < 5, so we don't add a tenth when rounding. Hence the answer is 2.4
5. . Because 
isn't divisible by 2 or 5, we know that this is the most simplified form.
6. Putting the I before the V negates the I. So IV = 5 - 1 = 4.
The answer maybe 40%, which means 19.6 kids prefer cats, which means the answer should be 20
