Question

-6+5(8-k)-8k


pleasee explain to me how to get the answer. i dont know how to do this kind of operation! thanks

Answer 1

-6+5(8-k)-8k

The first thing that you need to do is distribute the 5 to everything in the parenthesis. In other words, multiply everything in the parenthesis by 5:

-6 +5(8) +5(-k) -8k
-6 +40 -5k -8k

Now you need to combine like terms. Combine all your numbers and everything with a k:

34 -13k

Now, was your equation equal to zero? If so, you need to solve for k. If not, your answer is above. You didn't have your equation equal to anything, but if it is supposed to equal zero, here is what you would do:

34 - 13k = 0

To solve for k, move everything that doesn't have a k to one side, and everything with a k to the other side:

-13k = -34

Now divide both sides by -13 to find out what one k equals:

k = 34/13

Answer 2

-6+5(8-k)-8k

First, do the multiplying since that's done before adding/subtracting. The 5 outside ( ) gets multiplied by both things inside so it's

-6 + 40 - 5k - 8k

Now combine the like terms (things with k and things with no k)

34 - 13k

That's the answer, and how you do it

Answer 3

-6 + 5(8 - k) - 8k

To simplify this expression, first apply the distributive rule to the + 5(8 - k) to get + 40 - 5k

The distributive rule is stated as a(b + c) = ab + ac, and you must be careful of the signs

-6 + 5(8 - k) - 8k
- 6 + 40 - 5k - 18k {dsitribute}
34 - 23k {combine like terms}

Answer 4

-6+5(8-k)-8k

First, you do multiplication because of PEMDAS. So you distribute the 5 and you get -6+40-5k-8k. Then you add like terms and you get 34-13k. There you go.

Answer 5

first, you neeed to distribute, or multipy 5 times 8 and 5 times -k
this gives you 40 and -5k
now you have -6+40-5k-8k
you can combine -6 and 40, which add up to 34
then, you can combine -5k and -8k, which add up to -13k
that leaves you with -13k + 34 or 34 - 13k (they are the same thing, just in a different order
good luck!

Answer 6

multiply 5(8-k) and get 40-5k

then put it together:
-6+40-5k-8k

next add the k values, then the regular numbers:

(-6) +(40) = 34
(-5k) + (-8k) = -13K

add them together for the answer, which is:

34-13k

Answer 7

-6+5(8-k)-8k

-6+(5x8-5k)-8k

-6+40-5k-8k
break it apart:

-6+40 -5k-8k
34 -13k

Answer: 34-13k

PS: This is not an equation! Dont listen to anybody who tries to figure out what k equals! You are simply reducing here.

Answer 8

distribute the parenthesis

5(8-k) = 40-5k

so

-6+40-5k-8k
becomes
34-13k

Answer 9

ok i think this is how you can do this first you do (8-k) you need to know what k is though and then you do multiply -8 times k then you multiply what you got for (8-k) times what you got for -8k then you add -6+5 when you get that times what you got for (8-k) times -8k and i think thats how you do that

Answer 10

-6 +5(8-k)-8k
-6 +40 -5k -8k
34-13k
i think
