-12x² + 11x - 3 = 0
x = <u>-(11) +/- √((11)² - 4(-12)(-3))</u>
2(-12)
x = <u>-11 +/- √(121 - 144)</u>
-24
x = <u>-11 +/- √(-23)
</u> -24
x = <u>-11 +/- i√(23)</u>
-24
x = <u>-11 + i√(23</u>) x = <u>-11 - i√(23)</u>
-24 -24
x = ¹¹/₂₄ - 0.0416√(23) x = ¹¹/₂₄ + 0.0416√(23)

Answer:
37/40
Step-by-step explanation:
Divide by 5 to both numbers, since they both end in a 0 or 5.
185/5= 37
200/5= 40
I believe this is your answer since it cannot be simplified anymore.
What I am not sure what you are asking for me to answer
Step-by-step explanation:
90 nickels = 5*90=450=450/100=$4.5,
16 dimes=16*10=160=160/100=$1.6
16 quarters = 25*16=400=400/100=$4
7 fifty-cent pieces = 7*50=350=350/100=$3.5
Total dollars = 4.5+1.6+4+3.5=$13.6
