If x = 4, you would replace the “x”s with 4’s! So the problem would work out to be 4^2 - 4 over 4 - 8. 4^2 = 16. You would then subtract. 16 - 4 = 12. Now your problem is 12 over 4 - 8. 4 - 8 = -4. Now your problem is 12 over -4. So now you just divide. 12 / -4 = -3! -3 should be your answer! If you need me to write it out to show you I’d be happy to! Hope this helps! :)

6. You made cookies for a bake sale. You sold 24 cookies. This was 75% of the cookies you made. How many cookies did you make?​
3241004551 [841]

Answer: 32 cookies

Step-by-step explanation: Divide 24 by 3 to find 25% of the cookies you made. 24 divided by 3 is 8. Multiply 8 by 4, since 25% of your cookies times 4 would give you 100% of your cookies. 8 x 4 = 32 cookies.

Mykel is picking out some movies to rent, and he has narrowed down his selections to 66 foreign films, 33 children's movies, 66
uranmaximum [27]

Answer:

Mykel can make 2.79 x 10³² different combinations

Step-by-step explanation:

We can solve this problem using combination

The formula for combination is ⁿCₐ = \frac{n!}{(n - a)!a!}

where n = total number of choices available

a = number of items being chosen

The total movies Mykel wants is 99.

Taking out the sure 66 drama movies,

Mykel is left with 99 - 66 choices = 33 choices.

The total number of choices he is left with is 66 foreign + 33 children + 44 documentaries = 143 movies

Hence, our n = 143 movies

and a = 33 choices

Hence we do, ¹⁴⁴C₃₃ = \frac{143!}{(143 - 33)!33!} = \frac{143!}{110!33!} 2.79 x 10³² combinations

∴ Mykel can make 2.79 x 10³² different combinations.
