Answer:
You would want to divide 6 by 2, getting x=3.
Answer:
15 and 5 hours.
Step-by-step explanation:
Call x the time taken by the first chap, and y the second.
Let's divide by 5 and play with the LHS of the first equation a bit:
we know how much x+y is ( first equation!) let's solve.
At this point it's easy to check that 
Answer:
B is the answer

Step-by-step explanation:
You want the to find the value of k such that the y coordinate of the vertex is 0.
0=x2−6x+k
The x coordinate, h, of the vertex is found, using the following equation:
h=−b2a
h=−−62(1)=3
Evaluate at x = 3:
0=32−6(3)+k
k=9
Answer:
x = 4
Step-by-step explanation:
2.5x +6 = 3.25x +3
-2.5x -2.5x
6 = 0.75x +3
-3 -3
3 = 0.75x
divide by 0.75 both sides
4 = x
or
x = 4
