In your change cup you have 28 coins. All of which are nickels and quarters. Together they add up to $4. How many coins do you have of each.
Answer:
Step-by-step explanation:
In an isosceles trapezoid, the opposite sides are equal.
The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of The bases are the 2 sides of the trapezoid which are parallel with one another.
h represents the height of the trapezoid.
From the information given,
a = 6
b = 8
height = 16
Therefore,
Area of trapezoid = 1/2(6 + 8)16
= 1/2 × 14 × 16 = 112 square units
Infinitely many, because if you simplified the right side, it would equal the left side.
2x+8=20
2x=20-8
2x=12
12/2=x
6=x
