I subtract 2x to 8x that is equal to 6x; then I subtract 10 from right to left. So 94-10 equal 84. Now you got 6x=84, divide 6 both side and you got the answer.
The answer is x= 14
The correct proportions are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The proportions for this problem are given dividing y by x, hence:
- x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
- x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
- x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
- x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
- x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
- x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.

Answer:
A
Step-by-step explanation:
A is a parabola
Option c (9,2)
option c (9,2)
We know that the sum of all angles in a triangle = 180°
Angle (A+B+C) = 180°
or
(3x°+13) + (x°-8) + x° = 180
5x° + 5 = 180°===> 5x° = 175° & x =35°
