The area of a trapezoid is
A = (1/2) (h) (b1 + b2).
( 'h' is the height of the trapezoid. 'b1' and 'b2' are its two bases.)
You want the equation solved for one base.
A = (1/2) (h) (b1 + b2).
Multiply each side by 2 : 2A = h(b1 + b2)
Divide each side by 'h' : 2A/h = b1 + b2
Subtract b1 from each side: <em>2A/h - b1 = b2</em>
first one is 4 and the second one is two if i did it right. look up mathaway.com the calculator has this all and solves them for you . its a algebra calculator
X = The amount of cd's
Y = Jewelry sets
X + Y = 50
X + 8y<_50
20 + 8Y<_50
Subtract 20 from both sides.
8Y<_30
Divide by 8 on both sides
Y<_3.75 (3 total)
She can buy 3 jewelry sets.
Answer: $14.25
Step-by-step explanation:
Plug in 20 for x.
