14. trapezoid
- the bases are parallel
15. rhombus
- if you add 57 and 33 you will get 90 degrees. that means all the other angles the diagonals create intersecting each other are 90 degrees, and one of the properties of a rhombus is they have perpendicular diagonals.
16. kite
- two adjacent sides are congruent, and the two angles drawn are congruent
(a)
So here's the information we know:
Tanya bought 3 items
Tony bought 4 items
Tony's items were all 2.50 less than Tanya's
So, our equation should look like this:
3x = 4(x - 2.25)
(b)
3x = 4(x - 2.25)
3x = 4x - 9
-x = -9
x = 9
Tanya spent = 9 (x)
Tony spent = 6.75 (x - 2.25)
(c)
3(9) = 4((9) - 2.25)
27 = 36 - 9
27 = 27
or
Tanya: 3x = 3 (9) = 27
Tony: 4( x - 2.25) = 4(9-2.25) = 4(6.75) = 27
(d)
We can conclude that Tanya bought 3 items with a cost of $9 each, and Tony bought 4 items with a cost of $6.75 each. Both Tanya and Tony spent a total of $27.
