Select each equation that the number 10^2 makes true. 0.031 x __ = 31
0.501 x __ = 501
4.08 x __ = 408
0.97 x __ = 97
0.55 x __ = 550

4.08 x 10^2 = 408 = true

0.97 x 10^2 = 97 = true

Step-by-step explanation: the third and fourth equations are true

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.
