5d - 7 = -13
5d = -13 + 7
5d = -6
d = -6/5
Step-by-step explanation:
-x+2y=-6
x-2y=6
x=2y+6
substitute in 2x-3y=11 gives us 2(2y+6)-3y=11
4y+12-3y=11
y=-1
-x+2(-1)=-6
-x=-4
x=4

Step-by-step explanation:
The question is asking to put the photographers into least to greast.
For the best case, I suggest you change them into decimals and put them in order.
Photgrapher A: 2/5 = 0.4 = 40%
Photographer B: 4% = 0.04 = 4%
Photographer C: 0.29 = 29%
