How much are they selling the shirts for ? how much debt do they have ?
Answer:
100% --- x
75% --- 18
knowing that you have to multiply the 100 with 18 and 75 with x
75x = 100 . 18
75x = 1800
x = 1800 : 75
x = 24

Answer:
Step-by-step explanation:
The diagonals of the parallelogram are A(-5, -1), C(-1, 5) and B(-9, 6), D(3, -2).
Slope of diagonal AC = (5 - (-1)) / (-1 - (-5)) = (5 + 1) / (-1 + 5) = 6 / 4 = 3/2
Slope of diagonal BD = (-2 - 6) / (3 - (-9)) = -8 / (3 + 9) = -8 / 12 = -2/3
For the parallelogram to be a rhombus, the intersection of the diagonals are perpendicular.
i.e. the product of the two slopes equals to -1.
Slope AC x slope BD = 3/2 x -2/3 = -1.
Therefore, the parallelogram is a rhombus.
I think the current age of the child is 16 and the father is 40. That would mean 4 years ago the father was 36 and the child was 12. This makes the father 3 times as old as his son four years ago.
