Geometry help please!

Algebra is number 3 - You have subtracted the measure of angle HKI from the equation.

Transitive property of equality is number 2 - Because both pairs of angles equal 180 degrees, you can set them equal to each other.

Definition of congruence is number 4 - The congruence symbol is in the equation, which tells you that the two angles are congruent.

Angles forming a linear pair sum to 180 degrees is number 1 - 180 degrees is in the equations given and the angles all form linear pairs.

Hope this helps!! :)

Solve it by Substitution

30 in each bus. 17 in each van

To solve this problem, we first have to create a system of equations. After that, you set the equations equal to each other, and use that to simplify and find the value of one variable. Once that is found that answer can be plugged into one of the two original equations to find the other variable.

A lawyer charges a $75 consultation fee and then $120 per hour thereafter.
Ainat [17]

Answer:

(a) The dependant veriable is the $120 per hour and the independant veriable is the $75 consultaion fee.
(b) The table of vaules for this would look like this,
\frac{C}{T} \frac{75}{0} \frac{195}{1} \frac{315}{2} \frac{435}{3} \frac{555}{4}, where C = cost and T = time.
(c) The relationship between C and T is linear, beacause with the more hours you take the cost increases.
(d) Yes, it is sensible because the points would be in line due to the steady increase of the hourly rate.

(e) For every hour spent the cost increases 120 dollars.
(f) The fixed cost is 75 dollars for consultation and the veriable cost is 120 per hour.

105t = distance of eastbound train

95t + 105t = 440

200t = 440

t = 2.2 hr.
