Given thatP(5,4) Q(8,10) and R (X,18) are collinear. Find X
aleksley [76]

Answer:

x = 12.

Step-by-step explanation:

If P(5,4),Q(8,10) and R(x,18) are collinear

then the slope of PQ equals the slope of QR

hence:

(10 - 4)/(8 - 5) = (18 - 10)/(x - 8)

6/3= 8/(x - 8)

2 = 8/(x - 8)

multiplying both sides by (x - 8) gives:

2(x - 8) = 8

2x - 16 = 8

2x = 8 + 16 = 24

hence x = 12

0v0 h e l p? <br><br> 3r/4=1/8 (solve for r)
agasfer [191]

Answer:

r = 1/6

Step-by-step explanation:

\dfrac{3}{4}r=\dfrac{1}{8}\\\\\\

Multiply both sides by 4

4*\dfrac{3}{4}r=4*\dfrac{1}{8}\\\\3r = \dfrac{1}{2}

Divide both sides by 3

\dfrac{3}{3}r=\dfrac{1}{2*3}\\\\r = \dfrac{1}{6}

Barbara, Mark, and Carlos participated in the third heat of “The Big Race”. Barbara thought she could win with a 3 meter head st
steposvetlana [31]
Distance to travel = 20 m.
Let us determine the time, t, that each participant took to complete 20 m.

Barbara:
Average speed = (3 m)/(2 s) = 1.5 m/s
t = 20/1.5 = 13.3 s

Mark:
t =  5 s

Carlos:
y = x + 1
where
y = 20 m
x = time, t
Therefore
t =x = y - 1 = 20 - 1 = 19 s

Summary:
Barbara:  13.3 s
Mark:       5 s
Carlos:     19 s

Answer:
The winner is Mark
