Which of these procedures is the same as multiplying a whole number by 100? (a) multiply the whole number by 2, ten times. (b) move the decimal point two places to the left and fill in the blank places with zeros (c) move each digit of the whole number to the left and fill in the blank places with zeros (d) add 100 to the whole number, 2 times.

C) Move each digit of the whole number to the left and fill in the blank places with zeros

Step-by-step explanation:

When we multiply a number by 10, we add a zero to the right of the whole number.

2 * 10  = 20

When we multiply a number by 100, we add 2 zeros to the right of the whole number

2 * 100 = 200

However many zero's there are after the 1, when we multiply , we move the whole number by that many places and fill them with zeros.

∞ this is your sign

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.
