We know
In a function
x represents the input and y represents output
So
x is time
So
f(30) represents distance traveled in 30mins
Answer:
12 and 36
Step-by-step explanation:
Call the age of both Bill and his father is a and b, respectively
we have:
b=3a
b-3=4(a-3) ->b=4a-12 -> 3a=4a-12 ->a =12 -> b=36
This should be easy.
6.97 rounded to the nearest 10th is 7.00

Answer:
117 students
Step-by-step explanation:
13/100 = X/900
(13 * 900)/100 = 117
Brackets first
2 * 6b is 12b
2 * 5 is 10
first part is 12b +10
The equation now is 12b + 10 is equal to 2 + 4b
take 2 from both sides
12b + 8 is equal to 4b
take 12b from both sides
8 is equal to -8b
divide by 8
1 is equal to -1b
