Hi There!
-----------------------------------------------------
Baseball Bats:
43 x 0.45 = $19.35 as the amount off.
43 - 19.35 = $23.65 with the discount.
23.65 x 2 = $47.3 for two bats.
-----------------------------------------------------
Glove:
28 x 0.25 = $7 as the amount off.
28 - 7 = $21 with the discount.
-----------------------------------------------------
Together:
21 + 47.3 = $68.3 as the total before taxes.
-----------------------------------------------------
With Taxes:
68.3 x 0.055 = $3.7565 as the tax amount.
68.3 - 3.7565 = $64.5435
-----------------------------------------------------
Answer:
Not Rounded: $64.5435
Rounded: $64.54

Hope This Helps :)
CosA=(21^2+23^2-25^2)/2*21*23
cosA=345/966
A=cos^-1(345/966)
A=69.08
1) to this case you must match both equations
3x+2 = 2x-3 ⇒3x-2x = -3-2⇒x= -5
now the value of x substitute it in the any of two equations, y = 3(-5)+2 = -13
and the other equation is the same value
y = 2(-5)-3 = -13
the point is ( -5,-13)
Each dvd cost $7.50 how? Your friends buy 8 dvd's and in total is 60, you want to divide 60 from 8 and find that it's 7.50 and then multiply 8 to 7.50 and it should be 60. Hope this helps!!
