<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>
3(-3 + 5x) -1 (4 - 4x)
Simplify each term by first using the distributive property with each set of parenthesis:
3*-3 + 3*5x - 1*4 -1* -4x
Now do the multiplications:
-9 + 15x -4 + 4x
Combine like terms
15x +4x - 9 -4
19x - 13
Hehehe I wish A lallaalalalal
Answer:
=5803.28$ and 1760.99 $
Step-by-step explanation:
Given that Emile Zola, a senior Manager for Timber eye industries in California got a merit raise of 7.25% and cost of living 2.2%
Total increase in percent = 
After rise Emile salary is 87609.50 $
Let Emile salary -- 100
RIse -- 9.45
Salary after rise -- 109.45
THus we get if 109.45 is raised salary then merit increase =7.25
Hence for 87609.50, merit increase = 
=5803.28$
Similarly we have cost of living increase=
=
