To evaluate the expression (7 + 5 \times 2 - 6), follow the order of operations (PEMDAS/BODMAS). First, calculate the multiplication: (5 \times 2 = 10). Then, substitute back into the expression: (7 + 10 - 6). Finally, perform the addition and subtraction: (7 + 10 = 17) and (17 - 6 = 11). Thus, the result is (11).

5 multiplied by 26 equals 130.
(3 times 2) + 4 times (7-1) = 30
7 x 7 = 49 6 x 7 = 42 49 - 42 + 2 = 9

It is: 8+7 = 15
(7-3)^2 plus (7-1)^2 = 16+36

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!
5+21= 26 26/7= 3.7 3.7-6= -2.3
To evaluate the ratio MH plus pH 3 divided by MH plus pH 7, first determine the molar concentration of each species at pH 3 and pH 7 using the Henderson-Hasselbalch equation. Then calculate the ratio of the concentrations of MH at pH 3 to pH 7, and divide this by the ratio of pH 3 to pH 7.
