So, its 18.5 per person
<span><span>
80/5=16
18.5-16=2.5
They would each save 2.5 dollars each.</span></span>
I think that the answer is 550 people on the cruise. i used my math notes
-x² + 8x - 6 = 0
x = <u>-(8) +/- √((8)² - 4(-1)(-6))</u>
2(-1)
x = <u>-8 +/- √(64 - 20)</u>
-2
x = <u>-8 +/- √(44)
</u> -2<u>
</u>x = <u>-8 +/- 2√(11)
</u> -2
x = <u>-8 + 2√(11)</u> x = <u>-8 - 2√(11)
</u> -2 -2<u>
</u>x = 4 - √(11) x = -8 + √(11)

can be simplified to by adding the 7 and 10 to get

.

cannot be simplified any more by combining like terms.
By distributing the 2b into the parentheses, you can simplify the expression:

Here you can just add:

Thus, the only expression that cannot simplify any more using adding like terms is the second,

.
(9-4) + 3•8 = 29
Explanation
First you need to apply the PEMDAS rule
Parentheses
Exponents
Multiplication
Division
Addition
Subtract
So when solving the problem you first have to solve what’s in Parentheses first. So (9-4) which would equal 5
Next, according to the PEMDAS rule you’d have to do multiplication next. So 3•8 is equal to 24
And finally, the last step is Addition. After you’ve done the Parentheses and Multiplication you have to add up your answers. 5+24 would be 29
Answer= 29
