There are 83 full price and 140 half-price admissions.
Two equations needed : x + y = 223 and 5x + 2.5y = 765
Use the first equation, x + y = 223 and rearrange it to fit the problem and substitute : y = 223 - x
5x + 2.5(223 - x) = 765
5x + 557.5 - 2.5x = 765
2.5x + 557.5 = 765
2.5x = 765 - 557.5
2.5x = 207.5
2.5x ÷ 2.4 = 207.5 ÷ 2.5
x = 83
_______________________
Now just subtract 223 and 83 to get the others:
223 - 83 = 140
Answer: No. To the contrary, "12,000,000" is the "standard form" of
"1.2 times 10 to the POSITIVE 7 power.
That is; "12,000,000 = 1.2 * 10⁷ " .

Answer:
do you need to simplify or solve for x?
Step-by-step explanation:
Answer:
x = 3.5
Step-by-step explanation:
6x + 5 = 2(2x +6)
6x + 5 = 4x + 12
6x - 4x = 12 - 5
2x = 7
x = 7/2 = 3.5
