So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y
she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve
we have
180=3x+2y and
x=15+y
subsitute 15+y for x
180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y
solve for x
x=15+y
x=15+27
x=42
she spent $42 on each sister
First you would take 312 and divide it by 13. Using that answer and put it over 1. Then times the answer that you just got by twelve. Then put that in a mixed number in its simplest form.

Step-by-step explanation:
Hello :
(4x^3)(2x)^-4=(4x^3)<span> (2^-4)(x^-4)
=(4/16)(x^-1) = 1/4x</span>
7/8 of a pound is 14oz
So if 14oz is 2/3 of the whole bag, you can divide 14oz by 2 to get the weight of 1/3 of the bag (Which is 7oz)
14oz + 7oz = 21oz total pounds of cashews in the bag
