When QS=6x and CS=5x-8, what is AB?

Mathematics
1 answer:
patriot [66]4 years ago
4 0

Answer:

AB = x+ 8

Step-by-step explanation:

Given : QS=6x and CS=5x-8

From the given figure,

QS = QC + CS

We are given with  QS  and CS

Replace it the above equation

6x = QC + 5x -8

Solve for QC

Subtract 5x on both sides

x = QC + -8

Add 8 on both sodes

QC= x + 8

QABC is a rectangle

QC = AB

So AB = x+ 8

nalin [4]

Answer:

1\ h\ 8\ min

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

\frac{140}{35}=\frac{x}{17}\\\\x=17(140)/35\\\\x=68\ min

therefore

68\ min=1\ h\ 8\ min

Please help me with number 55 &amp; 56. I need the answer very quick.<br>Use the point-slope formula
AlekseyPX
55.
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

56.
Same explanation as above.
x = 2
