The scores for the final exam in an 8th Grade Math class are listed: 58, 72, 74, 92, 84, 40, 74, 81, 76, 83.

What is the lower quartile score on the final exam?

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

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
