Answer:
The correct answer is B) 1/9
Step-by-step explanation:
In order to find this answer, you need to take the fraction that answered it on the first try and subtract the number that changed their mind.
5/18 - 1/6
In order to complete this operation, you need to give them common denominators.
5/18 - 3/18 = 2/18
And we can simplify that answer.
2/18 = 1/9
<u><em>Answer:</em></u>

<u><em>Step-by-step explanation:</em></u>
Simplify each term.
x/2+2x/3+1
To write x2 as a fraction with a common denominator, multiply by 3/3.
x/2⋅3/3+2x/3+1
To write 2x/3 as a fraction with a common denominator, multiply by 2/2.
x//2⋅33+2x/3⋅2/2+1
Write each expression with a common denominator of 6, by multiplying each by an appropriate factor of 1.
x⋅3/6+2x⋅2/6+1
Combine the numerators over the common denominator.
x⋅3+2x⋅2/6+1
Simplify each term.
7x/6+1
Y=mx+b is slope-intercept form
Ax+by=c is standard
Y-y1=m(x-x1 is point slope
Isolate specific variables using inverse operations to convert between these
In one minute printer can make 12/3=4 photos
1st box so in 4 minutes it will make 4*4 = 16 photos
2nd box 24 images will be in 24/4= 6 minutes
3rd box in 9 minutes it will make 9*4=36 images
4th box 40 images will be 40/4=10 minutes
