is this an algebra class? if so it just
11.50x + 16y = 20.25
500 shirts / 3 hours = 166 2/3 shirts per hour.
Divide total shirts by shirts per hour:
1800 / 166 2/3 = 10.8 hours.
Answer:
x= 10
Step-by-step explanation:
Since the triangles are congruent
<B = <E
50 = 5x
Divide each side by 5
50/5 = 5x/5
10 =x
Answer:
10
Step-by-step explanation:
sin30° =
= 
You find a parallelogram area by this formula:

Where
b is its base and
h, its height.
You get
b's value applying distance between two points formula.
If A and B points form the base:

And
h is the perpendicular distance between both bases.
