Answer: <u>A. -6=n</u>
Step-by-step explanation:
3(x - 2) =7x+n
3x-6=7x+n
-6=4x+n
-6=4(0)+n
-6=n
Given:
Total tips = $ 77.40
Ratio of tips sharing = 2 : 3 : 4
To find:
How much more does Brian get over Paul
Solution:
Let 2x, 3x and 4x be the cost of tips got by Paul, Colin and Brian.
Total cost of tips =$ 77.40
2x + 3x + 4x = 77.40
9x = 77.40
Divide by 9 on both sides.

x = 8.6
Brian gets = 4(8.6) = $34.4
Paul gets = 2(8.6) = $17.2
Difference = 34.4 - 17.2
= 17.2
Therefore Brian gets $17.2 more than Paul.
87 ° to radians in terms of pi =
=> 87 ×

=>

The principle behind this conversion is that we know that π radians is equal to 180 thus we are simply 'rationalizing' to include π in the answer.
You would add.
So the equation would be 1 3/4+1/4 which equals 2.
I hope this helped!:)
