Divide the distance by the amount of time it traveled:
640/11 = 58.18 Mph
Answer:
The solution of equation 
is 0.53,-7.53.
Step-by-step explanation:
Given : Quadratic equation
To find : The solution of equation ?
Solution :
The solution of the quadratic equation 
is 
Here, a=1, b=7 and c=-4.
Substitute the values,
Therefore, the solution of equation is 0.53,-7.53.
Problem 16 Begin by setting corresponding positions equal to each other.
9 = x + 2y and 13 = 4x + 1
The second equation only has one variable so you should solve it first.
13 = 4x + 1
13 - 1 = 4x + 1 - 1
12 = 4x (divide both sides by 4)
3 = x
you can use this value to find y in the other equation
9 = 3 + 2y
9 - 3 = 3 - 3 + 2y
6 = 2y
3 = y
Answer:
none
Step-by-step explanation:
110 + 60 = 170
but 170 is obviously not 180 sooo none will be 60 degrees
