Which expression shows 40.54 in expanded form? (4 x 10) + (5 x 1/10 ) + (4 x 1/100 )
(4 x 1) + (5 x 1/10) + (4 x 1/100 )
(4 x 10) + (5 x 1) + (4 x 1/100 )
(4 x 10) + (5 x 1) + (4 x1/10 )

It's the first option

Step-by-step explanation:

4 x 10 = 40

5 x 1/10 = 5/10 = 1/2 = .5

4 x 1/100 = 4/100 =.04

40 + .5 + .04 = 40.54

answer: the answer is 35%

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
