6. An urn contains 75 marbles. 50 marbles are blue and the remaining marbles are green
(a) What is the probability of drawing a green
marble?
(b) If 25 blue marbles are removed from the
urn, what is the chance of drawing a blue
marble

25/75 or 1/3 chance of green 25/50 or 1/2 chance of blue

Step-by-step explanation:

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

exactly you go it
