Answer:Walnuts cost $1.25 and chocolate chips cost $3.25
Step-by-step explanation: Make walnuts x and chocolate chips y.
3x+5y=20
6x+2y=14
Multiply the first equation by 2 and then subtract it from the second.
-(6x+10y=40)
6x+2y=14
-8y=-26
y=3.25
Plug y back into either equation and isolate x to solve for x.
6x+2(3.25)=14
6x+6.5=14
6x=7.5
x=1.25
Answer:
8 -7/16 y+4/5 p - 3/8 y
-7/16 y -3/8 y expand fraction so it would turn to
-7y/16-3y/8
multiply by 2 on the 3/8 to get a common demominator
-7y/16-6y/16
-7y-6y/16
collect like terms
-13y/16
rewrite fraction
- 13/16y
so the whole equation would turn into
8-13/16y+4/5p
