Answer:
4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
Step-by-step explanation:
Let A, B and C be the required expression, according to Associative property;
(A+B)+C = A+(B+C)
This shows that no matter the sum of values in parenthesis, it does not alter the values at both sides.
From the given expression, the expression that is equivalent using the Associative Property of Multiplication is 4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
Note that the product of the values in bracket do not affect the final values
4(2a ⋅ 5) = 4(10a) = 40a
(4 ⋅ 2a) ⋅ 5 = 8a ⋅ 5 = 40a
You can see that both expressions gives the same values
Direct proportionality
2 inches/ 10 miles = 5 inches / x miles
cross multiply
2x = 50
divide both sides by 2
x = 25
The actual distance between the library and the bank is 25 miles
Hope this helps :)
For a lenght of a desk which needs to be 1 2/3ft long, Danielle can use 1 hole dollar bill and she will need 2/3ft more. 1/2ft*x=2/3ft, x=4/3.
So for lenght she will need 1 hole dollar bill and 4/3 of a dollar bill more.
For width of table she need 5/4ft. 1/2ft*x=5/4ft, x=5/2.
So for width of table she will use 5/2 of a dollar bill.
Hi !
