58 plus tip of .20
so
58 times 0.2 = 11.6 is the tip
now we add tax (Presuming we son't tax the tip)
58 times 0.07 = 4.06 the tax
so its
58 + 11.6 + 4.06 = $73.66 total cost
-72-4x^2+8x^3-36x/x-3
-4(18+x^2-2x^3+9x)/x-3
-4(-2x^3+x^2+9x+18)/x-3
-4(-2x^2x(x-3)-5x x(x-3)-6(x-3) )/x-3
-4 x(-(x-3) ) x (2x^2+5x+6)/x-3
-4 x (-1) x (2x^2 +5x+6)
8x^2+20x+24
Your final answer would be 14a-5c
Answer:
c=3
Step-by-step explanation:
First simplify like terms.
1+4c=7+2c
1+2c=7 (subtract 2c from both sides)
2c=6 (subtract 1 from both sides)
c=3 (divide by 2)
CHECK:
1+4(3)=7+2(3)
1+12=7+6
13=13
Yes!
