Just plug in the numbers:

4:  16 + 24 = 40  YES

5 = 25 + 40 ≠ 40 NO

8: 64 + 48 ≠ 40 NO

10: 100 + 60 ≠ 40 NO


So A. is the correct answer. Just to be sure:

-10: 100 + ( - 60) = 40 


Your answer is A. Hope that helps! :)

How are mountains and plateaus alike?
IgorLugansk [536]

Answer:

It is similar to a mountain in that it is dramatically higher than what is immediately around it. But mountains usually have a distinct apex or peak that is very small relative to the base and not typically level. Plateaus and mesas have tops only a little smaller than the base, and relatively flat. If the aspect ratio is less than 1, plateau. If greater than 1, mesa.

In how many different ways can a man divide 7 different gifts among his 3 children if the eldest is to receive 3 gifts and the o
krok68 [10]

The order in which gifts are received doesn't matter - if child X gets toy 1 then toy 2, it's the same as giving child X toy 2 then toy 1 - so we are counting combinations.

The eldest child receives 3 of the 7 gifts, so they have

\dbinom 73 = \dfrac{7!}{3!(7-3)!} = 35

possible choices of gifts.

The next child receives 2 of the remaining 4 gifts, so they have

\dbinom 42 = \dfrac{4!}{2!(4-2)!} = 6

choices.

The last child receives the remaining 2 gifts, and there is only

\dbinom22 = \dfrac{2!}{2!(2-2)!} = 1

way to select the gifts for them.

By the multiplication using, the total number of ways of distributing 7 gifts among 3 children in the prescribed way is 35 • 6 • 1 = 210.

What is the multiplicative inverse of 3y2?
kolbaska11 [484]

Answer:

A multiplicative inverse is a reciprocal. ... A reciprocal is one of a pair of numbers that when multiplied with another number equals the number 1. For example, if we have the number 7, the multiplicative inverse, or reciprocal, would be 1/7 because when you multiply 7 and 1/7 together, you get 1!

4+10(5-3) = 4 +62 is what?<br> O 18<br> O 42<br> O 21<br> O45
Shtirlitz [24]

Hey there!

4 + 10(5 - 3) = 4 + 62

4 + 10(5) + 10(-3) = 4 + 62

4 + 50 - 30 = 4 + 62

54 - 30 = 4 + 62

24 = 4 + 62

24 = 66

24 ≠ 66


OR

4 + 10(5 - 3) = 4 + 62

4 + 10(2) = 4 + 62

4 + 20 = 4 + 62

24 = 4 + 62

24 = 66

24 ≠ 66


Thus, this statement is FALSE because both of your numbers aren’t equivalent to each other.


But, let’s try this method

4 + 10(5 - 3) = 4 + 62

4 + 10(2) = 4 + 62

4 + 20 = 4 + 62

24 = 66

24 ≠ 66

66 - 24 = 42

Thus, if this is what your question is asking it would be: Option B. 42


Good luck on your assignment and enjoy your day!
