Answer:
The coefficient is the numerical value in front of the variable so some examples.
Ex: 3x
3 is the coefficient
Ex: 9x²
9 is the coefficient
Ex: x³
1 is the coefficient because in front of the variable there is an imaginary 1 if there is no numerical value in front of the variable.
Ex: -9x
-9 is the coefficient.

Answer:
<h2>18.750kg</h2>
Step-by-step explanation:
If a mass of 2.5 grams costs a penny, we want to know the amount of mass that will cost $75. Before we get the mass, we need to convert 75 dollars to penny. Using the conversion:
$1 = 100pennies
$75 = (75*100)pennies
$75 = 7,500 pennies
Using the law of equivalence
1 penny = 2.5 grams
7,500pennies = x grams
Cross multiply
1 * x = 2.5 * 7500
x = 18,750 grams
Hence 18,759 grams will cost $75
Converting grams to kilograms
If 1000 grams = 1kg
18,750grams -= y
cross multiply
1000*y = 18750
Divide both sides by 1000
1000y = 18750/1000
y = 18.750kg
<em>Hence the amount in kilogram of $75 coin in pennies is 18.750kg</em>
A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides.
