To solve 540 = 12z you have to use inverse operation by dividing both sides by 12 to get 45 = z

540 = 12z

the process that would be used most often would be division.

540 = 12z....divide both sides by 12
540/12 = z
45 = z <==

although, another procedure could also be used....multiplication..
540 = 12z...multiply both sides by 1/12
540(1/12) = z
540 /12 = z
45 = z <==

horsena [70]

Answer:

A tourist receives 2376 ec currency in exchange for us 1200.

Step-by-step explanation:

This can be calculated as follows:

Tax rate = 1%

Amount of us currency = 1200

Total amount of ec currency = Amount of us currency * 2 = 1200 * 2 = 2400

Amount of tax = Total amount of ec currency * Tax rate = 2400 * 1% = 24

Net amount of ec currency = Total amount of ec currency - Amount of tax = 2400 - 24 = 2376

Net amount ec currency obtained above is the amount of ec currency which a tourist receives in exchange for us 1200.

Therefore, a tourist receives 2376 ec currency in exchange for us 1200.

How many miles are equivalent to 3.1 kilometers? 1 kilometer is about 0.62 mile

Anton [14]

Answer:

1.922 miles is equivalent to 3.1 kilometers.

Step-by-step explanation:

Given:

1 km = 0.62 miles.

3.1 km = ? miles

Now, in order to find the number of miles equivalent to 3.1 km, we use unitary method with the help of the conversion factor.

From the conversion factor, we can conclude that kilometer is a smaller unit compared to that of mile.

So, conversion factor = $\frac{0.62\ miles}{1\ km}$

The formula to transform 'n' kilometers to miles is given as:

$=Conversion\ factor\times n$

Therefore, 3.1 km = $\frac{0.62\ miles}{1\ km}\times 3.1\ km$

3.1 km = $1.922$ miles

Therefore, 1.922 miles is equivalent to 3.1 kilometers.

=. What does the expression (x+3)(9) represent? Why?

tresset_1 [31]

Because when you multiply the 9 by x you get 9x and when you multiply the 9 by 3 you get 27. So then your final answer would be 9x + 27.
I hope this helps!! :)
