Answer:
25 feet
Step-by-step explanation:
This is a ratio question.
Say the ratio is object : shadow. Then, the person and their shadow is
5 : 4
If the shadow is 20, then the ratio is
flagpole : 20
How do you go from 4 to 20? You multiply by 5. So, if we multiply the person's height by 5, we'll get the height of the flagpole.
5 * 5 = 25 feet
Difference means subtraction (-)
Twice a number means × 2
is at least ≥
Put it all together
2b - 9 ≥ -15
Then you can solve for b
2b - 9 ≥ -15
2b ≥ -15 + 9
2b ≥ - 6
b ≥ - 6/2
b ≥ - 3
