A recent advertisement for "the fat burning pill", Lipozene, claims that people who have taken the pill have lost over 400% more weight. According to the ad, the claim was based on a clinical study consisting of two groups: the active group and the placebo group. They said that "during 60 clinical trials, the active group lost 2.75 lbs and the placebo group gained 2.18 lbs". Explain whether in your judgment, the statistics presented in this ad is meaningful, incomplete, misleading, or difficult to interpret meaningfully. Justify your statements by reasoning.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
