Earth has a surface area of approximately 197000000 square miles and a total land area of 58000000 square miles. what fraction of the earth surface is land? write another fraction that is close to your answer and has a denominator.

We have been given that the surface area of the earth is approximately 197000000 square miles.

Also the land area of the earth is given by 58000000 square miles.

Therefore, the fraction of the earth surface is land is given by

On simplifying it, we get

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
