The equation w= 3.1g + 6 can be used to estimate w, the weight of a puppy in ounces that is g weeks old.
Based on the equation, which statement compares the expected weight of a 1-week old
puppy to the weight of a newborn puppy?

hope you got it.

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
