Answer:
140 cm
Step-by-step explanation:
Given that:
Total length of ribbon present with Billy = 2.4 m
This ribbon is to be shared with 12 friends evenly.
Billy is doing this work of making craft for the past many years.
To find:
How many centimeters of ribbon that 7 friends will get?
Solution:
First of all, let us find out what length of ribbon will each person get.
Length of ribbon to be shared with each person = Total length of ribbon divided by total number of persons
Length of ribbon to be shared with each person = 
Now, The length of ribbon that 7 friends will get = 7
0.2 = 1.4 m
1 m = 100 cm
1.4 m = 1.4
100 cm = <em>140 cm</em>
Considering that the car does 50 miles per gallon, the linear function for the number of gallons of fuel in Jim's fuel tank, n, in terms of the number of miles x that Jim has driven since filling his tank is given by:

<h3>What is a linear function?</h3>
A linear function is modeled by:

In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- Jim's car holds 14 gallons of fuel, hence
.
- Considering it does 50 miles per gallon, and the amount in the tank will decrease, the slope is
.
Hence, the function is:

Answer: 1.2 grams
Step by step explanation : divide the mass value by 1000
X=4 because you combine 2+4 and subtract -6 then divide
3x^2 + 9x + 6 = 0
3x^2 + 3x + 6x + 6 = 0
3x(x + 1) + 6(x + 1) = 0
(3x + 6)(x + 1) = 0
3x + 6 = 0 and x + 1 = 0
3x = -6 and x = -1
x = -2 and x = -1
