Alana is working on creating a scale drawing of her mom's bakery store. She
has set her scale 1/2 in = 6 ft. If the
bakery store is 33 ft long, then how many
inches should it be on the scale drawing?
length - 33 feet

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.

3x^3-2x^2+4x-3= -3

x^2+3x+3= 3

-3÷3= -1
