If Jimmy has 530 pieces of paper and Kit comes along and gives him 18 times as much, how many pieces of paper Jimmy have? And if Kit takes 23 pieces away how much does Jimmy have now?

10,070 and 10,047 pieces respectively

Step-by-step explanation:

In this question, we have 2 questions to answer.

Firstly, we are told that Jimmy has 530 pieces of paper and kit comes along to give him 18 times as much, we need to know how much he has now.

Since he was given 18 times as much, the amount given would be 18 * 530 = 9,540

The amount he has now would be 9,540 + 530 = 10,070 paper pieces

Secondly, Kim comes along to take 23 pieces away, we need to know how much pieces he has now. What to do is simply to

Subtract 23 from the previous pieces = 10,070 - 23 = 10,047 pieces of paper

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
