Let's call the two numbers x and y. We can write a system of equations to describe the situation:

5x = 8y

x - y = 150

Let's solve the first equation for x:

x = 8y/5

Now we can use substitution to solve the system by plugging 8y/5 in for x in the second equation:

(8y/5) - y = 150

Simplify:

3y/5 = 150

3y = 750

y = 250

If y = 250, then x is:

x = 8(250)/5 = 400

The answer is 250 and 400.

stealth61 [152]

Answer: Charlotte finished the word search in 16 minutes.

Step-by-step explanation:

Frank finished the word search in 32 minutes.

Terrence finished a word search in 3/4 the time it took Frank. This means that the time it took Terrence to finish the word search would be

3/4 × 32 = 24 minutes.

Charlotte finished the word search in 2/3 the time it took Terrence. This means that the time it took Charlotte to finish the word search would be

2/3 × 24 = 16 minutes
