Answer 2

$\bf \:❥︎Answer:- 1$

Let 'x' represents the number of months and 'y' represents the total weight.

So, algebraic representation of above situation is

$\bf\implies \:y = 151 - 7x.....(1)$

$\bf \:❥︎Answer:- 2$

To get the weight after 5 months, put x = 5 in equation (1),

$\bf\implies \:y = 151 - 7 \times 5$

$\bf\implies \:y = 151 - 35$

$\bf\implies \:y = 116 \: pounds$

$\bf \:❥︎Answer:- 3$

The weight lose in 7 months = 7 × 7 = 49 pounds.
