7*46 = 7*(40 + 6) = 7*40 + 7*6 = 280 + 42 = 322
You multiply the outside number touching the parenthesis by the numbers inside. Ex: 6(x - 5) = 42 6x - 30 = 42 6x = 72 x = 12
42*23 = (40+2)*(20+3) = 40*20 + 40*3 + 2*20 + 2*3 = 800 + 120 + 40 + 6 = 966
fraction of 42 is 28 = 28/42 or 2/3
28/42 x 100 = % Answer = 66.66666 recurring % = 67%
Individual numbers do not have the distributive property - mathematical operations do.
(2 x 14) + (3 x 14) = 5 x 14 = 70
42 + 63 = (2 x 21) + (3 x 21) = 5 x 21 = 105
An unnecessary one. 42 + 96 = 138
The distributive property states that when you have a problem, say 3(42-36) then you distribute the multiply by 3 to the 42 and -36 to get 126-108 which can be easier to solve some times. Also when you simplify problems with variables, you can substitute 5n+15 to 5(n+3).-------a(b+c) = ab+ac
the property says that a+b+c is the same as a+c+b and it is the commutative property of addition.
7*46 = 7*(40 + 6) = 7*40 + 7*6 = 280 + 42 = 322
distributive property, and substitution property. EX: 42 x 20 = (40 + 2) x 20 = (40 x 20) + (2 x 20)
You multiply the outside number touching the parenthesis by the numbers inside. Ex: 6(x - 5) = 42 6x - 30 = 42 6x = 72 x = 12
Pick a pair of numbers. Let's try 30 and 42. Their GCF is 6. 6 x 5 and 6 x 7 By the distributive property, that can be written as 6(5 + 7)
42*23 = (40+2)*(20+3) = 40*20 + 40*3 + 2*20 + 2*3 = 800 + 120 + 40 + 6 = 966
3 x 42 = (3 x 40) + (3 x 2) 3 x 40 = 120 3 x 2 = 6 120 + 6 = 126 3 x 42 = 126
