Answer:
Image A shows a rotation.
<span>We know that OB bisects EC where they intersect would be at point O,
so the two lengths EO and OC must be equal.
2x - 20 = 70 - x
</span>[adding x + 20 to each side]
2x - 20 + x + 20 = 70 - x + x + 20
[simplifying]
<span>3x = 90
</span>[dividing each side by 3]
<span>
x = 30 would be the answer</span>
This is a proportion problem that involves cross multiplication
3/5 = x/650
650 x 3 = 1950
1950/ 5 =390
Or you could have done 650 x .6 (which is the decimal form of 3/5) and got 390 as your answer
