Answer:
The answer seems to be 3/1.
Step-by-step explanation:
Use the equation:
(y2-y1)/(x2-x1)
8.49/4 = 2.1225
Sunblock 1 costs $2.12 per ounce of sunblock.
10.29/5 = 2.058
Sunblock 2 costs $2.06 per ounce of sunblock.
Sunblock 2 is the better buy because it is cheaper ounce-per-ounce.
3x-6 = 7x +1
7x-3x= -(6+1)
4x=-7
x= -7/4
I hope this helps you
5=7x+0.1+10x-0.2
17x=5.1
x=5.1/17
x=3/10
x=0.3
