Step-by-step explanation:
8.35 < 3x + 18.75
3x + 18.75 > 8.35
3x > 8.35 - 18.75
3x > -10.4
x > -3.47
Answer:
<h3>Rational</h3>
Step-by-step explanation:
A rational number is the a number expressed as the ratio of two integers. 30.1458623 is a rational number because it can be expressed as the ratio of two integers as shown;
Since 301,458,623 and 10,000,000 are both integers hence 30.1458623 is a rational number.
Real, natural and whole number are not decimal in nature and since 30.1458623 is a decimal number, it is not classified as real, natural and whole number.
Irrational numbers are also classified as real number.
Hence 30.1458623 is classified as a rational number.
Hello!
The "Unit Price" (or "unit cost") tells you the cost per liter, per kilogram, per pound, etc, of what you want to buy.
Just divide the cost by the quantity:
Example: 2 liters for $3.80 is $3.80/2 liters = <span>$1.90 per liter. Hope this helps!</span>
