The 26 students in Mr. Welch’s class read a total of 65 books last month. The 24 students in Ms. Goldwasser’s class read a total of 66 books. On a average, how many more books did each student in Ms. Goldwasser’s class read than each student in Mr. Welch’s class?

the answer to this is a. a^2 + b^2 = c^2

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.

the answer is -81 is the answer
