A bag of blue and white marbles has 75 marbles in. There are nine more blue marbles than white. How many of each marble are there?

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

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

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
