Answer:
x = 3
Step-by-step explanation:
This is an isosceles triangle. Two angles (D and F) are equal because the sides opposite them are equal (or vice versa).
Thus, side DE = side EF, or
12x - 8 = 4x + 16
Combining like terms: 8x = 24
Thus, x = 24/8 = 3
x = 3
75% of 84 is what number
.75 x 84 = n (sentence above translated to math) Note what "of" means and what "is" means.
.75 x 84 = 63.
It is linear because it is a straight line when graphed. It is not proportional because there is not always a constant ratio between them.
