Answer:
70 cards
Step-by-step explanation:
Let A = the number of Andys cards
J = the number of Jons cards
Jon and Andy had a total of 560 trading cards
A+J = 560
After Jon gave 1/9 of his trading cards to Andy, they has an equal number of trading cards
J - 1/9 J = 1/9 J +A
Combine like terms
8/9 J = 1/9 J +A
Subtract 1/9J from each side
7/9J = A
Substitute this into A +J = 560
7/9J +J = 560
Combine like terms
7/9J +9/9J = 560
16/9 J = 560
Multiply each side by 9/16
9/16 *16/9 J = 560 *9/16
J =315
Jon originally had 315 cards
Now we need to find Andys cards
7/9J = A
7/9 (315) =A
245=A
How many more trading cards did Jon have that Andy in the beginning?
We need to take Jons cards and subtract Andys cards
J-A
315-245
70

Answer:
The probability is 
Step-by-step explanation:
B =business
J=jumbo
Or =ordinary
From the question we are told that
The proportion of the passenger on business in the ordinary jet is 
The proportion of the passenger on business in the jumbo jet is 
The proportion of the passenger on jumbo jets is 
The proportion of the passenger on ordinary jets is evaluated as
According to Bayer's theorem the probability a randomly chosen business customer flying with Global is on a jumbo jet is mathematically represented as
substituting values
Step-by-step explanation:
Answer: 22
<u>Step-by-step explanation:</u>
f(x) = 2x² - 3x + 8
f(-2) = 2(-2)² - 3(-2) + 8
= 2(4) + 6 + 8
= 8 + 6 + 8
= 22
The first is an absolute value sign. But there is a - outside the first one so the -4 does become positive but then becomes negative again so you have -4
The second value is basically saying the same thing as -1x-4 which become a negative times a negative which is positive. You end up with 4.
So no it does not equal each other.
I do see an extra absolute value symbol though on the right side of the equal sign. But it looks like either way it would be -4 = 4 and that's not true. So either way it should be false.
Sure where is the problem
