Select all the equations that have rational number
x³=8
x³=16
x³=27
x³=64

x³=8

x³=27

x³=64

Step-by-step explanation:

A rational number is one formed by dividing integers. This means a rational number can be expressed as a ratio of two integers. Examples of rational numbers are;

1/3 formed from ratio of 1 to 3 or 1 divided by 30.75formed from ratio of 3 to 4 or 3/44formed from the 4/13.45formed from 345/100-2.5formed from -25/10

Given in the question;

x³=8 x=∛8 = 2 can be formed from 2/1 ⇒ equation has rational number

x³=16 x=∛16 = 2.5198421 irrational

x³=27x=∛27 = 3rational

x³=64x=∛64 =4rational

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

Idon’t know what the answer is i wish i could
