The value of c for which the equation is identity is 6
Given the expression
|2x + 5|=|cx + 3 - 4x +2|
Collecting the like terms;
|2x + 5|=|cx - 4x + 3 +2|
|2x + 5|=|cx - 4x + 5|
If the <u>modulus is positive;</u>
2x + 5 = (c-4)x + 5
Compare both sides of the equation
2x = (c-4)x
2 = c-4
c = 2 + 4
c = 6
Hence the value of c for which the equation is identity is 6

We have to calculate the total weight of the three samples. After that we have to choose the correct answer. Weight of those three samples is: 0.170 grams, 0.204 grams and 2.300 grams. We simply have to find the sum of those weights: 0.170 g + 0.204 g + 2.300 g = 2.674 g. Answer: <span>C. 2.674 grams.</span>
