There are 5 red marbles, 7 green marbles, 4 black marbles, and 8 blue
marbles in a bag. Suppose you select one marble at random. Find each
probability.

red 21%

green 29%

black 17%

blue 33%

Step-by-step explanation:

total 5+7+4+8=24

red 5:24=0.21=21%

green 7:24=0.29=29%

black 4:24=0.16=17%

blue 8:24=0.33=33%

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
