Answer:

Step-by-step explanation:
we know that
Hunter was biking for 2 hours 20 minutes and covered 35 miles
so
using proportion
Find out how long would it take him to cover 17 miles on this bike
Remember that
1 h=60 min
2 h 20 min=2(60)+20=140 min
Let
x -----> the time to cover 17 miles

therefore

Answer:
x=3.5
Step-by-step explanation:
AD/BD=AC/BC
x/4.2=5/6
6x=21
6x/6=21/6
x=3.5
Hope this helps! ;)

The only type of line with undefined slope is a vertical line.
In a vertical line, all points have the same x-coordinate.
The general equation of a vertical line is x = k, where k is the x-coordinate of all points on the line. If you are given one point, then you know the x-coordinate of that point, but since all points have the same x-coordinate, you also know the x-coordinate of all points.
Equation is: x = -6

Same explanation as above.
x = 2
Answer:
the first one pretty sure
Answer:
1 Factor out the common term 22.
2(2x+y)=102(2x+y)=10
2 Divide both sides by 22.
2x+y=\frac{10}{2}2x+y=

3 Simplify \frac{10}{2}

to 55.
2x+y=52x+y=5
4 Subtract yy from both sides.
2x=5-y2x=5−y
5 Divide both sides by 22.
x=\frac{5-y}{2}x=

5−y
Step-by-step explanation:
