You have two fractions with the same (common) denominator, so you
subtract the numerators and put that over the common denominator.
Answer:
$297.50
Step-by-step explanation:
If she earns 105 for three hours, she would be earning $35 an hour.
105/3=35
If she works 8.5 hours, to find the amount you would multiply the hourly rate ($35) by 8.5. So, the answer is
8.5x35=$297.50

Step-by-step explanation:
-2g=?

To solve for the missing steps, let's rewrite first the problem.
Given:
In a plane, line m is perpendicular to line t or m⟂t
line n is perpendicular to line t or n⟂t
Required:
Prove that line m and n are parallel lines
Solution:
We know that line t is the transversal of the lines m and n.
With reference to the figure above,
∠ 2 and ∠ 6 are right angles by definition of <u>perpendicular lines</u>. This states that if two lines are perpendicular with each other, they intersect at right angles.
So ∠ 2 ≅ ∠ 6. Since <u>corresponding</u> angles are congruent.
Therefore, line m and line n are parallel lines.
