5x + 10           10
---------- =      -------
   121               11

make the bottom have same common denominator

10/11 x (10/10) = 100/121

Get rid of the denominator (for both now have 121 as a base)

5x + 10 = 100

5x + 10 (-10) = 100 (-10)

5x = 90

5x/5 = 90/5

x = 18

x = 18  is your answer

hope this helps

121/11 =11

10* 11 = 110

5x+10 = 110

5x = 100

x = 20

Im stuck on this question, plz help
denis-greek [22]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

40 metres covered in 6 seconds

Max speed attained after 6seconds

75 meters covered after 11 seconds

Average Speed for first 40 meters :

Speed = distance / time

Speed = 40m / 6s

Speed = 6.67m/s

To obtain the maximum speed :

Next (75 - 40) meters = 35 meters was covered in (11 - 6)seconds = 5 seconds

Speed at this point is maximum :

Hence, maximum speed = (35m / 5s) = 7m/s

Suppose, Manuel runs for an additional z seconds after reaching max speed :

Distance from starting line 6+z seconds after race started?

Distance after 6 seconds = 40 metres

Distance after z seconds = 7 * z

Total distance = (40 + 7z)

What is Manuel's distance from the starting line x seconds after the race started (provided x≥6x)?

Distance for first 6 seconds = 40 meters + distance covered after 6 seconds = (7 * (x-6))

40 + 7(x - 6)

Which is an equation in point-slope from for the given point and slope point (-2,4)slope:5
maks197457 [2]
<span><span>If we have a point, (x1;y1)<span> and a slope, </span>m, here's the formula we </span><span>use to find the equation of a line: y - y1 =m( x - x1); where x1 = -2 ; y1 = 4 ; m = 5.
Then, y-4 = 5(x+2);
Finally, y-4 = 5x + 10 / +4
y = 5x + 14 ;
