Step-by-step explanation:
there is no question for anyone to help you out
Step-by-step explanation:
the small and the large triangles are similar triangles.
they have the same angles. and the corresponding sides correlate to each other with the same ratio for every pair of sides.
so,
28 / 82 = (2x + 8) / ((2x + 8) + (5x -4)) =
= (2x + 8) / (7x + 4)
(7x + 4)×28 = (2x + 8)×82
196x + 112 = 164x + 656
32x = 544
x = 17
Slope AB = 1/3
slope CD = -3
Im not sure about the last part but I think the product of slope AB and slope CD is -1 so line AB is perpendicular to line CD.
the workings are below:)
(so sorry if it’s wrong)
Answer:
20% discount means
Previous price was $100 and now it’s
(100-20)=$80
$100 is now $80
So $1 is now =80/100 =$ 0.8
So $45 is now = 45x0.8 = $36
So she will save $45– $36 = $9
