Answer:
The linear equation is y = 6 x + 9
The graph is attached down
Step-by-step explanation:
The given information:
The cost of 1st km is 9 Rs
The cost of every kilometer after the first is 6 Rs
x represents the number of km
y represents the total cost of x km
The form of the linear equation is
y = m x + b, where
- m is the slope of the line (rate of change)
- b is the y-intercept (initial value)
From the given information above
m = 6 Rs/km
b = 9 Rs
Substitute them in the form of the equation
y = 6 x + 9
The graph:
Answer:
0.53
Step-by-step explanation:
A fraction bar can also mean division. So 8/15 the fraction also means 8÷15.
8÷15 = 0.5333333...
Rounding to the nearest hundredth means there should be only two numbers to the right of the decimal point.
8/15 ~= 0.53
Answer:
140 minutes
Step-by-step explanation:
First divide 21 by 3 to get 7
Then do 20*7 to get 140 :)
1. let x be the sold tickets for adults
3x be the sold tickets for students
x + 3x = 348
4x = 348
x= 87 tickets for adults
2. let x be the no. of books produced
41664 + 8.5x = 19x
41664 = 19x - 8.5x
41664 = 10.5x
x = 3968 books
