Andre sometimes mows Lawns on the weekend to make extra money. Two weeks ago he mowed a neighbor's lawn for half an hour and earned $10. Last week he mowed at his uncle's lawn for 3 1/2 hours and earned $30. This week he mowed the lawn of a community center for 2 hours and $30 which job paid better than others

he had a better pay when he mowed his neighbor's lawn.

Step-by-step explanation:

Two weeks ago he mowed a neighbor's lawn for half an hour and earned $10. This means that the amount that he would earn per hour is

10/0.5 = $20

Last week he mowed at his uncle's lawn for 3 1/2 hours and earned $30. This means that the amount he would earn per hour is

30/3.5 = $8.6

This week he mowed the lawn of a community center for 2 hours and $30. This means that the amount he would earn per hour is

30/2 = $15

Therefore, he had a better pay when he mowed his neighbor's lawn.

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
