Answer:
Step-by-step explanation:
When adding or subtracting rational expressions, it is easiest to find a common denominator.
Ex.

The common denominator would be 
We need to make both fractions have that denominator

Answer:
1.66 on the top and 5 on the bottom
Step-by-step explanation:
3 ÷5= 1.66
2÷10=5
A graphing calculator can be helpful for these.
A) Since neither inequality includes the "or equal to" case, the boundary line for the solution set is a dashed line. For the first inequality, the shading is above the line; for the second, the shading is below the line. The solution set is points to the right of perpendicular lines with slope -2 and +1/2 through point (2, -1).
B) The point -2, 3 satisfies, neither inequality.
.. 3 > -2(-2) +3 . . . FALSE
.. 3 < 1/2(-2) -2 . . .FALSE
The smallest would be 400,000 and the largest would be the same because 0 can't round up or down
Answer:
The answer to your question is: ∠4 = 140°
Step-by-step explanation:
If there are two parallel lines cut by a transversal line 8 angles are formed.
These angles are classified as corresponding angles, alternate exterior angles, alternate interior angles and same-side angles.
Alternate exterior angles measure the same. Also alternate interior angles measure the same.
Same-side angles are supplementary angles, that means that their sum gives 180°.
Finally corresponding angles measure the same.
In the figure we notice that angles 6 and 8 are same side angles, so:
∠6 + ∠8 = 180
and ∠6 = 40° 40 + ∠8 = 180
∠8 = 180 - 40
∠8 = 140°
and ∠4 and ∠8 are corresponding angles so,
∠4 = ∠8 = 140°
