49.5 / 71.5 = x / 97.5
x = 49.5 * 97.5 / 71.5
x = 67.5
answer
x = 67.5 ft
Set up a ratio:
10 foot tall elephant / X shadow length = 15 foot tall statue / 18 foot shadow.
Cross multiply:
10 * 18 = X * 15
Simplify:
180 = 15x
Divide both sides by 15:
x = 180 / 15
x = 12
The elephants shadow was 12 feet long.
or you can wirte like x ≈ 2.416
The answer is B.red
the reason:
if x=2
-2 (2)+ 5y = 10
-4 +5y = 10
5y = 10+4
5y = 14
y = 2.8
now we have the point (2 . 2.8) which is absolutely on the line -2x + 5y = 10
when we look for it we see that it's on the line b which means line b is -2x + 5y = 10
Answer:
Forgive me if I'm wrong, but if I am correct that would be 30 people.
