The formula for the area of a trapezoid is a=1/2h(b+b) express b in terms a,h,and b2
Lunna [17]

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>

Ginny is making homemade pizzas for her family. The recipe makes 70 ounces of dough, but she made more that to ensure she had en
Anastaziya [24]

Answer:

14 ounce

Step-by-step explanation:

Given that:

Ounces of dough used in making recipe = 70 ounces

Number of ounces frozen = 28 ounces

Number of pizzas made from dough left = 3

Number of ounces left = total made - number frozen

Number of ounces left = 70 - 28 = 42

Weight of pizza made :

Number of ounces left / number of Pizzas made

42 / 3 = 14

Hence, maximum weight of each pizza made will weigh more than 14 ounces

If 16+4x is 10 more than 14, what is the value of 8x?
sattari [20]
16 + 4x = 10 + 14

16 + 4x = 24.

4x = 24 - 16

4x = 8

x = 8 ÷ 4

x = 2

8x = 2 × 8

8x = 16

Final answer = 16.
