B. D=0.25n + 25
D=total n=number of hours 0.25=price per hour 25=the one time fee
Answer:
A is 10 dollar cheaper than B
Step-by-step explanation:
A : 40 dollars plus 45*2=90
90+40= 130 dollars
B:100 dollars 45*1=45
100+45= 145 dollars
To determine the measure of angle C. You would solve the equation for X. X+47=180. X= 180-47. X= 133. The measure of angle C is 133 degrees.
The marked angles are opposite angles, and as such they have the same measure. So, we have

Subtract 2a and 11 from both sides to get

Divide both sides by 4 to get

Now that we know the value of a, we can compute the measure of the angles. We can also verify that the solution we found is correct by verifying that both expressions actually give the same result:


Answer:
-17/18
Step-by-step explanation:
find least common multiple, which is 18
multiply the numerators by the number you multiplied on the denominator.
and subtract.
