This is a science question sryjoe was heating a test tube when it cracked. what could have caused it to crack? a. he held the test tube directly over the flame for too longb. he did not add water to the test tubea or b, explain tks

A is more likely. Heating something to fast and for too long can cause stress on the glass causing it to crack. Water wouldn’t have effected it

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.

-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
