The first thing we should know is the definition of commutative property.
Commutative property:
The distributive property of multiplication over addition in elementary algebra is that in which the result of a number multiplied by the sum of two or more addends is equal to the sum of the products of each summand by that number. In algebraic terms we have then:
4 * ((2 * 0.75) + (3)) = (8 * 0.75) + (4 * 3) = 6 + 12 = 18 $
answer:
the total cost of these parts is $ 18
Answer:
Step-by-step explanation:
The formula of a perimeter of a rectangle:
The formula of an area of a rectangle:
l - lenght
w - width
We have l = 3w and the perimeter P = 256 in. Substitute:
<em>divide both sides by 2</em>
<em>divide both sides by 4</em>
Calculate the area of a rectangle:
The triangle ABC is the half of the rectangle. Therefore the area of a triangle ABC is:
Well first you have to divide 620/20 which is 31. So his car goes 31 miles per gallon so you have 2 gallons and .25 of a gallon. So first off 2*31=62 miles then the 1/4 or .25. Multiply the 31 by .25 which is 7.75 now add 62 and 7.75 and you get how far his car can go.
62+7.75=69.75 miles
It is because the 35.4% divided the 100% total is B. 0.354
