Answer:
_<u>7</u> + 3 = 3 + 7 : commutative property,[if something is added or subtracted]
0 +<u>5</u> _ = 5 is it: identity property.[if 0 is added or subtracted]
2 + (6 + 8) =(2 + 6)+ _<u>8</u> associated property
[if added or multiplied]
Because they show exactly how much of something is there/needed.
Using the distributive property we know we distribute by multiplying the outside values to those inside of the parentheses
outside values: 2
inside values: 5 and r
now multiply out inside values by the outside values
2x5 = 10
2xr = 2r
now plug these values back in for the inside values and take away the outside value and the parentheses
so 2(5+r) using the distribution property is 10+2r
Answer:
First find the amount of tax paid, by subtracting the total amount paid from the cost of the item:
530 - 500 = 30
Now divide the amount of tax paid by the cost of the item:
30 / 500 = 0.06
Multiply by 100:
0.06 * 100 = 6% tax
