Answer:
I think it would be 11.5
Step-by-step explanation:
To find out if the given value is a solution of the equation, substitute/plug it in to see if it equals out:
1. 34 + x = 46; x = 12 Plug in 12 into "x" since x = 12
34 + 12 = 46
46 = 46
The given value is a solution of the equation because it does equal 46
2. y - 9 = 14; y = 22 Plug in 22 into "y" since y = 22
22 - 9 = 14
13 = 14
The given value is not a solution of the equation because 22 - 9 equals 13 not 14
3. 6d = 54; d = 9 Plug in 9 into "d" since d = 9
6(9) = 54
54 = 54
The given value is a solution of the equation because it does equal 54
4. ; n = 39 Plug in 39 into "n" since n = 39
13 = 13
The given value is a solution of the equation because it does equal 13
Answer:
Skater 500 m / 40 sec = 12.5 m/ sec
Cheetah 260 / 10 = 26 m/ sec
The cheetah is more than twice as fast as the skater.
