Which of the following statements about a variable are true? a, a variable is represented by a letter. b, a variable cannot be subtracted. c, a variable represents a quantity. d, a variable cannot be multiplied.

Ithink the answer is discovery verbs because they are quite similar to the verb 'discovering'

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
