Answer:

If the correction of 6 * 6X is accurate then I hope this is the answer.

Step-by-step explanation:

6(6x)+3x=3+3x+5

1. First multiply 6 by 6

36x+3x=3+3x+5

2. Then add 36X and 3X

39x=3+3x+5

3. After that add 3 and 5

39x=3x+8

4. Subtract 3x from both sides of the equation.

39x−3x=8

5. Subtract 3x from 39x

36x=8

6. Divide

36X. 8

______. = ______

36. 36

7. 36X and 36 cancel out because they

are common factors

8. The common factor between 8 and 36 is 4.

S you are left with. 2

X= _____

9. If you would like the decimal, than it is, X = 0.2

Vera_Pavlovna [14]

Answer:

It is 91.01 m/s faster than the Singaporean sprinter

Convert km/hr to m/s

U get 101.38m/s (speed of bullet train)

Speed of the Singaporean sprinter is 10.37m/s

So subtracting the train speed from the sprinter's speed,

101.38 - 10.35= 91.01m/s
