Rosa has a bookshelf where she stores her book collection. four tenths of her books are mystery books. what is this amount written as a decimal?

0.4

Step-by-step explanation:

4/10 is the same as 0.4 because tenths place is one place after the decimal point. So it would be 0.4

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

your answer is d 2,500
