According to PEMDAS, you should do the parenthesis first, then the multiplication, then the subtraction. Let's do it:
75-(8+45/3)*7
= 75-(8+15)*7
= 75- 23*7
= 75- 161
= -86.
Hope this helps~

Answer:
They did not leave the correct amount. They left around a 22% tip
Step-by-step explanation:
15% = 0.15
68.25(0.15)
10.24
22% = 0.22
68.25(0.22) = 15.02
0.8% of 75 is 6
convert 0.8% to decimal (0.08)
convert 0.08 to fraction (2/25)
x times 2/25 equals 6
multiply each side by the reciprocal of 2/25 (25/2)
2/25 times 25/2 equals one
6 times 25/2 equals 75
so x equals 75

Hello
I believe there is an error in the question
we have two equations and need to find x and y
let s multiply by 8 so that we can get rid of the fractions
(1) becomes 2x+4y=5
(2) becomse 6x-4y=9
if we sum it gives
2x+4y+6x-4y=9+5
8x=14
x = 14/8 = 7/4
and then from the first equation
4y = 5 - 7/4
<=> 16y = 20-7 = 13
y = 13/16
the solutions is (7/4,13/16)
