The numbers are 16,24 and 32

Step-by-step explanation:

The question in English is

The arithmetic mean of 3 numbers is 24. The second number is 50% greater than the first and the third is one third greater than the second. What are the numbers?

Let

x---> the first number

y ---> the second number

z ---> the third number

we know that

The arithmetic mean of 3 numbers is 24

so

----> equation A

The second number is 50% higher than the first

Remember that

so

----> equation B

The third number is is one third greater than the second

Remember that

so

----> equation C

substitute equation B and equation C in equation A

solve for y

Find the value of x

Find the value of z

therefore

The numbers are

16,24 and 32

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
