Convert into kilometer 213 km 42 m

213.042  km

Step-by-step explanation:

We need to convert 213 km 42 m to km.

We know that,

1 km = 1000 m

or

1 m = (1/1000)km

So,

42 m = (42/1000) km

It means,

So, the required answer is 213.042  km.

10

step-by-step explanation:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
