Answer from: kob3965

To find between what two consecutive whole numbers the square root of a number is, we find the perfect square of each number, until the result passes the desired number.Whole numbers: Countable, that is, 0, 1, 2,3,...The square of a number x is x^2

Doing this, we get that the square root of 68 lies between 8 and 9.

Squares:

The square of 0 is 0^2 = 0

The square of 1 is 1^2 = 1

The square of 2 is 2^2 = 4

The square of 3 is 3^2 = 9

The square of 4 is 4^2 = 16

The square of 5 is 5^2 = 25

The square of 6 is 6^2 = 36

The square of 7 is 7^2 = 49

The square of 8 is 8^2 = 64

The square of 9 is 9^2 = 81

68 is between, 64 and 81, thus, the square root of 68 is between the square root of 64 and the square root of 81, that is, the square root of 68 is between 8 and 9.

Answer from: alliuhhh0

You want to know the two numbers that squared are on either side of 68.

8^2 and 9^2=64 and 81

So the two consecutive numbers are 8 and 9

Answer from: Quest

starting with:

5 + x - 12 = 2x - 7

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)

5 - 12 = x - 7 (combine and cancel x's from both sides)

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)

0 = x (add numbers together on both sides)

so in order for the equation to be true, x must be 0.

trying x = -0.5

5 + x - 12 = 2x - 7 (original equation)

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)

5 + -0.5 - 12 = -1 - 7 (did multiplication)

-7.5 = -8 (did addition on both sides)

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.

trying x = 0

5 + x - 12 = 2x - 7 (original equation)

5 + 0 - 12 = 2(0) - 7 (plug in value of x)

5 + 0 - 12 = 0 - 7 (did multiplication)

-7 = -7 (did addition on both sides)

since -7 equals -7, that demonstrates that the value of 0 for x is correct.

trying x = 1

5 + x - 12 = 2x - 7 (original equation)

5 + 1 - 12 = 2(1) - 7 (plug in value of x)

5 + 1 - 12 = 2 - 7 (did multiplication)

-6 = -5 (did addition on both sides)

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
