Mark has a six-sided number cube. each side is numbered from 1 to 6. what is the probability, expressed as a ratio, that mark will roll a 3? a) 1 1/2 b) 1/6 c) 2/6 d) 1/2

➷ There is only one '3' on the cube

Therefore, it would be B. 1/6

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
