Answer:

Compare the cost for the each (smallest) unit.

Step-by-step explanation:

You can calculate the cost per unit

For example :

20 ounces of water of brand A cost 1.50

30 ounces of water of brand A cost 2

20 ounces of water cost 1.50/20 = 0.075 dollar per ounce

30 ounces of water cost 2/30 = 0.0677 dollar per ounce

Answer:

True

Step-by-step explanation:

6x² - 4y - 3x + 6x² + 8x = 12x² + 5x - 4y

Answer: $RM 31631$

Step-by-step explanation:

We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:

$RM 57000(\frac{8}{9})^{n}$

Where $RM 57000$ is the price of the car when it was bought new, and $n=5$ is the number of years the car was used.

Solving the formula with the given data:

$RM 57000(\frac{8}{9})^{5}=RM 31630.95$ This is the value of the car according to the formula.

However, this value can be approximated to:

$RM 31631$

HELP!!!! PLEASE I NEED HELP!!!!

NNADVOKAT [17]

for the first one it is the second option because of one property of logarithms:

log(a)-log(b)=log $\frac{a}{b}$

for the second one using the same property we can say that we third option is correct and not the second one but we use one more property of the logarithm

loga(b)^x=xloga(b) the power of the logarithm becomes a fator and $\sqrt[3]{x}$ is equal to $x^{\frac{1}{3}}$
