If Alex and Brandon work together, they will finish cleaning the school in 15 hours. Working alone, Brandon can finish the same

andriy [413]

Answer:

Alex can do the job in 60 days alone.

Step-by-step explanation:

Alex and Brandon working together, they can finish the job of cleaning the school in 15 hours. Brandon alone in 20 hours can finish the job.

So, Brandon can complete $\frac{1}{20}$ part of the job in one hour.

Let, Alex alone can finish the same job in x hours.

So, Alex can complete $\frac{1}{x}$ part of the job in one hour.

So, working together they do $(\frac{1}{20} + \frac{1}{x}) = \frac{x + 20}{20x}$ part of the whole job in one hour.

Hence, from the conditions given we can write

$\frac{x + 20}{20x} = \frac{1}{15}$

⇒ 15x + 300 = 20x

⇒ 5x = 300

⇒ x = 60 days.

Therefore, Alex can do the job in 60 days alone. (Answer)

A clown needed 275 balloons for a party he was going to, but the balloons only came in packs of 2.How many packs of balloons doe

atroni [7]

For this case what you need to know is that each package contains 2 balloons.
Therefore, you can solve the problem by making the following rule of three:
1 package ---> 2 balloons
x ---------------> 275 balloons
Clearing x we have:
x = (275/2) * (1)
x = 137.5
Nearest whole number:
x = 138
Answer:
I need to buy 138 packs of balloons
