You and four friends have been given a group project to work on in your school. You do 2/5 of the work. (i) Is this fair? why or why not?

no.

Step-by-step explanation:

let's assume that fair means 1/5 effort you should give anything less or more seems like not fair. and 2/5>1/5

No.

Step-by-step explanation:

You with your four friends makes five people

if you do 2/5 of the work and rest all does 1/5 of the work then 1 person doesn't have to do the work.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
