Dea writes the expression 0.25 + 0.76 + 0.75 + 0.24. she rewrites the expression using the commutative property. which expression could dea have written using the commutative property?
a) (0.25 + 0.76) + (0.75 + 0.24)
b) 0.25 + 0.75 + 0.76 + 0.24
c) (0.25 + 0.76) − (0.75 + 0.24)
d) 0.25(1 + 1)

B )  0.25 + 0.75 + 0.76 + 0.24

Step-by-step explanation:

commutative law of addition:-

According to the commutative property of addition,changing the order of the numbers.we are adding doesn't change the sum.

let a,b,c+d are two numbers

The commutative property condition in addition a+b+c+d = a+c+b+d

Given expression 0.25+0.76+0.75+0.24 = 0.25 + 0.75 + 0.76 + 0.24

conclusion:-  Answer B.

answer: 12

step-by-step explanation:

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
