Which expression is equivalent to 2(m − 5) + 6?2m − 1

2m + 22

2m − 4

2m + 16

Answers

Answer 1
Answer:

The expression that is equivalent to 2(m - 5) + 6 is 2m - 4. Option C is correct.

The given algebraic equation consists of numbers, arithmetic operations, and variables. The first thing to do is to open the brackets. After that, we will sum up or subtract the like terms.

Given that:

  • = 2(m - 5) + 6
  • = 2m - 10 + 6
  • = 2m - 4

Therefore, we can conclude that the expression that is equivalent to 2(m - 5) + 6 is 2m - 4.

If a vector pointing upward has a positive magnitude, a vector pointing downward has a negative magnitude. True or false?

Answers

Answer:

The statement is false.

Step-by-step explanation:

For any vector 'r' we have

\overrightarrow{r}=x\widehat{i}+y\widehat{j}+z\widehat{k}

The magnitude is given by

|r|=\sqrt{x^(2)+y^(2)+z^(2)}..........(i)

As we know that the upon squaring a term the result is always positive thus the term in right side of equation i is always positive no matter weather the terms (x,y,z) are positive or negative hence we conclude that magnitude of any vectorial quantity is always positive irrespective of it's direction.

A jewelry maker will use 24 blue beads and 30 green beads to make necklaces. What are the possible number of necklaces she can make if each necklace has the same number of blue and green beads? How many of each type will be on each necklace?

Answers

Answer:

  • 1 necklace: 24 blue, 30 green
  • 2 necklaces: 12 blue, 15 green (each)
  • 3 necklaces: 8 blue, 10 green (each)
  • 6 necklaces: 4 blue, 5 green (each)

Step-by-step explanation:

The greatest common factor of 24 and 30 is 6. The divisors of 6 are 1, 2, 3, and 6. Those are the numbers of identical necklaces that might be made from the beads. The number of beads of each color is found by dividing the total number of beads by the number of necklaces being made.

The possible numbers of necklaces are 1, 2, 3 or 6.

The numbers of (blue, green) beads on each will be (24, 30), (12, 15), (8, 10), or (4, 5), respectively.

_____

The greatest common factor (GCF) is the product of the common prime factors.

  24 = 2^3×3

  30 = 2×3×5

The prime factors in common are 2 and 3, so the GCF is 2×3 = 6.

What is a 2 digit number, less than 50 that can be divided by 4 exactly and when 4 is added to it it can be divided by 5 exactly

Answers

ok

divisible by 4 exactly measn that it is even
ends with 0,2,4,6,8

when you add 4 it divides by 5, if it is divisble by 5 it ends with 0 or 5
the possible numbers under 50 that are divisble by 5 are
5,10,15,20,25,30,35,40,45

if you add 4 to the mystery number, you get divisible by 5
minus 4 from all of that list and see which s divisible by 4
1,6,11,16,21,26,31,36,41
