Answer:
3x -2y = -5
Step-by-step explanation:
Standard form is ...
ax +by = c
where the leading coefficient (a, or b if a=0) is positive and a, b, c are mutually prime.
Multiplying the equation by 2 gives ...
2y = 3x +5
We can subtract 2y+5 to get standard form:
3x -2y = -5
Answer:

Answer:
$68 and $10.792
Step-by-step explanation:
The computation is shown below:
The total bill received by them is $56.80
The total bill after adding 19% tip is
= Total bill + tip amount
= $56.80 + 19% of $56.80
=$56.80 + $10.792
= $67.592
= $68
The sever would make the amount i.e. equivalent to the tip amount i.e $10.792
37.5% = 3/8 as a fraction.
So 180 x 8/3 would get you your answer.
Solution: 480
