The question has a typo (It is 3 years older than 2/3 times Lily's age). I attached the correct question below.
Answer:
Lily is 24 years old
Explanation:
Assume that Lily's age is x and that Hilitary's age is y.
We are given that:
Hilitary's age is 3 years greater than 2/3 times Lily's age
This means that:
y = (2/3 x) + 3
Now, we are given that:
Hilitary's age is 19 years old.
This emans that : y = 19
Substitute with y = 19 in the above equation and solve for x as follows:
y = (2/3 x) + 3
19 = (2/3) x + 3
19 - 3 = (2/3) x
16 = (2/3) x
48 = 2x
x = 48/2
x = 24

The correct way to write that is 309,058,304.
It helps if you say it out loud to yourself. that is what helped me! ☺

Answer:
f = 108
Step-by-step explanation:
p = f/a [p = 27 and a =4]
27 = f/4 [multiply 27 and 4 to get 108]
check your work: 108/4 = 27

The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
Substituting:
The volume of the frustum is given by the formula:
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
