3x + 7 = 3(-3) + 7= -9 + 7= -2
(3 times 2) + 4 times (7-1) = 30
5X + 2X + 7 when X=2 Replace X with 2 (5x2) + (2x2) +7 Work parenthesis first 7 + 4 + 7 Answer 7 + 4 + 7 = 18
It should be evaluated as a major calculation error!
pH 3 is 10^-3 and pH 7 is 10^-7 which is the same as saying 0.001/0.0000001 which equals 10,000!
5+21= 26 26/7= 3.7 3.7-6= -2.3
7 x 7 = 49 6 x 7 = 42 49 - 42 + 2 = 9
