Answer:
600 + 40 + 8 + .2 + .09 + .007 = 648.297
Answer:
v = 87
Step-by-step explanation:
the angle v+39 lies on a straight line. so substract v+39 from 180 to get the interior angle for that side.
afterwards, knowing that the sum of interior angles of a triangle = 180, form an equation with all the angles and solve for v
(1) let there be x book and let the total cost be y dollars.
y=19.25x+40
y=16x+69.25
(2) 19.25x+40=16x+69.25
3.25x=29.25
x=9
9 silver book, 9 gold book.
(3) y=19.25x+40=19.25*9+40=213.25 dollars
both companies' total cost are 213.25 dollars.
<span>valid. She used a representative sample
</span>because she correctly found the average and 18,000 is a reasonable number to get for a the problem
