Answer:

x=6

Step-by-step explanation:

you subtract 7.7 from both sides

12.4x+7.7-7.7=82.1-7.7

then you're left with

12.4x=74.4

divide by 12.4 on both sides

12.4x/12.4=74.4/12.4

x=6

What set or sets of real numbers does -√16 belong to?
Sati [7]

Answer:

Step-by-step explanation:

Well the square root of 16 can be simplified to 4, which can be represented as a fraction: 4/1, so it's not irrational, but rather rational.

Whole numbers are similar to integers, and natural numbers, the only difference is integers includes all real numbers, which do not have a decimal value. So this includes negative numbers, zero, and positive numbers.

Whole numbers include all real numbers, which do not have a decimal value, and are greater than or equal to zero, or in other words, not negative.

Natural numbers include all real numbers, which do not have a decimal value, and are greater than zero, or in other words, positive numbers.

So this number is a integer, and rational number. (since the negative number in front of the radical)
