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

Ella takes 1 3/5 hours to complete a painting. Holly takes 3/4 of the time that Ella takes. How long will Holly take to complete
Misha Larkins [42]
1. you have to figure out what 3/4 of Ella's time is.
1 \frac{3}{5}  =  \frac{8}{5}
(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)
\frac{8}{5}  = 8 \div 5 = 1.6
\frac{3}{4}  = 3 \div 4 = .75
3. Next you are going to divide 1.6 by .75
1.6 \div .75 = 2.13
4. Now multiple 2.13 by 5.
2.13 \times 5 = 10.65
Answer is 10

17. What expression is equivalent to log(200) - log (2)? Calculate the answer.
IRINA_888 [86]

Answer: 2

Step-by-step explanation:

Recall from the laws of Logarithms:

Log a - Log b = Log ( a/b )

That means

Log 200 - Log 2 = Log ( 200/2)

= Log 100 , which could be written as

Log 10^{2}

Recall from laws of Logarithms:

Log a^{b} = b Log a

Therefore:

Log10^{2} = 2 Log 10

Also from law of Logarithm

Log 10 = 1

Therefore 2 Log 10 = 2 x 1

= 2
