Answer:
what exactly is this question
Step-by-step explanation:
Answer:
here down is the answer
(2y/5y)^3+4y^2+6y
8y^3/125y^3 +16y^2+6y
8/125+16y^2+6y
8/125+16y^2+6y=0
16y^2+6y+8/125=0
it is in the form of quadratic equation
formula :
x=(-b+-square root of b^2-4ac) /2a
here a=16,b=6&c=8/125
x=(-b+-square root of b^2-4ac)/2a
x=(-6+-square root of 36-4.09)/2a here 4.09 came by calculation
x=(-6+-31.91)/2
so
x=(-6+31.91)/2 first (+);
x=25.91/2
x=12.955;
x=(-6-31.91)/2 then(-);
x=-37.91/2
x=-18.955 ;
ans is = 12.955&-18.955;
The equation is 12x = 15,000 and the answer is x = 125. 125 is how many rides you use so 15,000 people get to ride.
I'm assuming that each price copied twice, since 5.225.22 isn't a number.
To find the percent, divide the tip by the meal cost:
5.22 ÷ 29 = 0.18 = 18%
Jerry left an 18% tip.
To find the total cost of the meal, add the tip and the meal cost:
5.22 + 29.00 = 34.22
The total cost if the meal, including tip, was $34.22.
