The rates of each cyclist are 17mi/h and 20mi/h
What is rate?
Rate is a ratio that compares two different quantities which have different units.
In this comparison, one unit is taken to be a standard unit in which the other is compared with.
Analysis:
Let the speeds of both cyclists be x, x+3
distance travelled by x cyclist = 2x
distance travelled by (x+3) cyclist = 2(x+3)
Total distance = 2x + 2(x+3) = 74 miles
2x +2x +6 = 74
4x + 6 = 74
4x = 74 - 6
4x = 68
x = 68/4 = 17mi/h
The other cyclist speed is x +3 = 17 +3 = 20mi/h

Answer:
The question is unclear
Step-by-step explanation:
Answer:
1/2 or 0.5
Step-by-step explanation:
If there is 2 cats and 2 dogs it would be 2/4, simplify 2/4 you get 1/2. Same with a decimal number 0.25 for each, half is 0.5. I hope that works, sorry if it doesn't!
Answer = $39.78
100-20 =80
100-25=75
Multiply 60 x .80 to get $48
Then multiply 48 x .75 to get $36
Sales tax %10.5 = move decimal two places to left .105
Now multiply 36 x .105 =3.78
$3.78 equals your sales tax
Finally add $3.78+$36= $39.78
The answer is
-2x + 4y - 0.4
