\\ \sf\longmapsto (3x-2x^2+3)-(-5x^2+3x+5)

\\ \sf\longmapsto 3x-2x^2+3+5x^2-3x-5

\\ \sf\longmapsto 5x^2-2x^2+3x-3x+3-5

\\ \sf\longmapsto 3x^2-2

Emily thinks the perfect tomato sauce has 8 cloves of garlic in every 500{ mL} of sauce. Raphael's tomato sauce has 12 cloves of
igomit [66]

For perfect solution we need to have :-  8 colves   in 500ml    solution

500   ml     has   8 cloves

1 ml             has     8 / 500 cloves

100ml         has   8 / 500  * 100  =    8/5  = 1.6 cloves

Raphael's mixture  

    900 ml  has 12 cloves

      1 ml     has   12 / 900 cloves

   100 ml has   12 / 900 *  100   =    12 / 9  =   1.33 cloves

so concentration of garlic in 100 ml solution of Raphael's solution is less than Emily's solution    so it is not garlicky enough.     ( option B)

Ethan’s football team scored a total of 35 separate times this season, with a mix of touchdowns and field goals. Each touchdown
nadya68 [22]
I do not have a Inspire calculator with me at the time. But I do have the equation you can enter into Solve systems (systems of equations or whatever they call it )
x=touchdowns
y=field goals


x+y=35
7x+3y=193

once you get the results x will still stand for touchdowns and y stands for field goals, and there's your answer.

hoped I helped a little.
