Answer:
7 ( x - 0.75 ) = 2.80
Step-by-step explanation:
7 ( x - 0.75 ) = 2.80
7x - 5.25 = 2.80
7x = 2.80 + 5.25
x = 8.05/7
x = 1.15
------------------------------
1.15 - 0.75 = 0.4
(0.4)*7 = 2.8

PH is calculated by the negative logarithm of the hydrogen concentration in a solution. Therefore, the pH in this case is:
pH = -log (0.0000006)
pH = 6.22
Therefore the correct answer among the choices is the last option, pH of 6 with a color pink.
Formula for this case is
(a+b)∧3=a∧3+3a∧2b+3ab∧2+b∧3
(2x+5)∧3=(2x)∧3+3*(2x)∧2*5+3*2x*5∧2+5∧3=8 x∧3+3*4x∧2*5+3*2x*25+125=
=8x∧3+60x∧2+150x+125
Good luck!!!
