30% = 0.3.
0.3*80 = 24, so we know that 30% of 80 is 24.
80 - 24 = 56, so after the sale, the price for a pair of jeans is $56.
10% = 0.1
0.1*56 = 5.6, so with the coupon, we get $5.60 off.
56 - 5.60 = 50.40
The jeans cost $50.40 after the sale and the coupon.

Answer:y= -2/5x-3
Step-by-step explanation:
It's actually pretty simple, all you gotta do is flip the fraction around so if it is 5/2x now is 2/5, and then change the sign, since it was positive now it's negative
Step-by-step explanation:
b.3n/2 = 7/2
6n = 14
n = 2 1/3
c.-x/2 + 6 = -13/4
-x/2 = -37/4
-4x = -74
x = 18 1/2
d.3x/10 = 2/5
15x = 20
x = 1 1/3
e.x/10 = -20/3
3x = -200
x = -66 2/3
f.269x/56 = 10
269x = 560
x = 2 22/269
