Answer:
I think Jenny had more consistent scores
X=number of adult tickets
y=number of child tickets
I suggest this system of equations:
x+y=144
9x+6y=1164
we can solve this system of equations by substitution method.
x=144-y
9(144-y)+6y=1164
1296-9y+6y=1164
-3y=1164-1296
-3y=-132
y=-132/-3=44
x=144-y
x=144-44=100
Answer: the theatre sold 100 adult tickets and 44 child tickets.
answer:35x^2
Step-by-step explanation:

Answer:
1.99750312 * 10 ^(-12)
Step-by-step explanation:
When we divide numbers in scientific notation
1.6*10^12
----------------
8.01 * 10^23
We divide the numbers out front and subtract the exponents on the powers of 10
(1.6/8.01) * 10^(12-23)
.199750312 * 10^(-11)
But this is not proper scientific notation. We need 1 number in front of the decimal. If we move the decimal 1 place to the left, we subtract 1 from the exponent
1.99750312 * 10 ^(-11-1)
1.99750312 * 10 ^(-12)
