Answer:
510
Step-by-step explanation:
1.5r+15=2.25r
First of all, you have to arrange the numbers according to those similar to them. So that will be;
15=2.25r-1.5r
1.5r is subtracted from 2.25r because it crossed over an equality sign to get its position close to 2.25r. And when a number crosses over an equality sign, the sign on the number chages to the opposite. 1.5r has an invisible positive sign which became negative when it crossed. Anyway;
2.25r-1.5r is the same as 2.25-1.5. And that is 0.75r
Therefore;
15=0.75r
To find out what r is, you have to divide the both sides by 0.75. This is done to remove the 0.75 close to r to finally reveal what r is. Anyway;
15/0.75=0.75r/0.75
15 divided by 0.75 is 20. And 0.75r divided by 0.75 is r. So;
20=r
r=20. So the answer is 20 movies. Hope i helped. Have a nice day.
Answer:
n= 2/-7
Step-by-step explanation:
2/n = -7
Multiply by n: 2= -7n
Divide by -7: n= 2/-7, or n= -0.286

<span>“Decimal”
comes from the Latin root decem, which simply means “ten.” The

one.</span>
In common language, the word
“decimal number” has come to mean numbers which have digits after the decimal
point, such as 5.8 or 9.302. But any number within the decimal number system
could be designate a decimal number, involve whole numbers such as 12 or 381.
<span>A Decimal Number (<span>based on the number 10</span>) contains a Decimal Point.</span>
<span>Here is the number "forty-five and six-tenths" written as
a decimal number:</span>
The decimal point goes between Ones and
Tenths.
45.6 has 4 Tens, 5 Ones and 6
