Scalene triangle: a triangle where all the sides are different and all the angles are different.
First you had to subtract by seventeen from both sides of equation form.
Then simplify.
Next, subtract by seven-p from both sides of equation form.
Simplify.
Then you divide by negative six from both sides of equation form.
And finally, simplify by equation.
Final answer: 
Hope this helps!

You drove for half the time at 60mph and the other half the time at 30mph.
To find your average speed, we add 60 and 30 then divide them by two (because you drove at 2 different speeds). 60+30 = 90 and 90/2 = 45 so 45 miles per hour is your average speed.
Note: Velocity implies a direction to the force and there is no direction in this question, just speed. Without direction we cannot use velocity, only speed.
Answer:
first evening = 21 phone calls
second evening = 11 phone calls
third evening = 84 phone calls
Step-by-step explanation:
Total phone calls = 116
Let
Number of calls in the first evening = x
The second evening = x - 10
The third evening = 4x
Total phone calls = first evening + second evening + third evening
116 = x + (x - 10) + 4x
116 = x + x - 10 + 4x
116 + 10 = 6x
126 = 6x
x = 126 / 6
x = 21 phone calls
Number of calls in the first evening = x
= 21 phone calls
The second evening = x - 10
= 21 - 10
= 11 phone calls
The third evening = 4x
= 4(21)
= 84 phone calls
118/13= 9 1/13
