Answer:
4.9
Step-by-step explanation:
Answer:
1/4 belongs to b. irrational numbers
Step-by-step explanation:
If you converted it into a decimal, it would only be .25.
If it was a number like pi, then it would be an irrational number because is no end.
Answer:
x=5 because if y=6 and x=2 the you subtract 2 from 6 and that's 4 so if you subtract 4 from 9 that will give you your answers of 5
Answer:
The distance of the run is 10 miles
The distance of the bicycle race is 69 miles
Step-by-step explanation:
Let:
- r = the distance for the run
- 79 - r = the distance for the bicycle race
- t = the time of the run
- 5 - t = the time of the bicycle race
The run: r = 5t
The bicycle race: 79 - r = 23(5 - t)
Simplify the bicycle race:
- 79 - r = 115 - 23t
- -r = 36 - 23t
- r = 23t - 36
Now we have two equations set up for r
We know that r = r, so 5t must equal 23t - 36
- 5t = 23t - 36
- 5t + 36 = 23t
- 36 = 18t
- t = 2
Now we know that the run took 2 hours.
Plug it back into the equation for the run to find the distance for the run
The run is 10 miles
To solve for the bicycle race, we simply subtract 10 from 79, because we know that the two distances combined are 79.
The bicycle race is 69 miles.
