Answer:
$29.41
Step-by-step explanation:
You know the discount price is 25 and the original is unknown so call it x. The sale is 15% off and that means that the jeans are 85% of what they used to be since 100-15 is 85. Then you plug it into a formula of 25/x = 85/100 then you cross multiply to get 2500=85x and when you solve for x and round you get $29.41
Answer:
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
Therefore, ∠ABC + ∠BAC + ∠BCA = 180°
⇒ 42 + 64 + ∠BCA = 180°
⇒ ∠BCA = 180 - 42 - 64

Answer:
(x, y) = (0, -1)
Step-by-step explanation:
The coefficients of x are opposites, so we can eliminate x by adding the two equations.
(6x +y) +(-6x -4y) = (-1) +(4)
-3y = 3 . . . . simplify
y = -1 . . . . . . divide by -3
Now, we need to find x.
6x -1 = -1 . . . substitute for y in the first equation
6x = 0 . . . . . add 1
x = 0 . . . . . . divide by 6
The solution is (x, y) = (0, -1).
