Alex’s printer can print 8 photos in 12 minutes. Khalil’s printer can print 24 photos in 1 hour.
Select all the processes you could use to help determine how much longer it will take Khalil’s printer to print 120 photos than Alex’s.

Write an equation that adds the number of photos that each printer prints in 1 hour.

Make a table of equal ratios to find how long it takes each printer to print 120 photos and find the difference.

Subtract the number of photos that Khalil's printer prints in 2 hours from the number of photos that Alex's printer prints in 2 hours.

Graph a table of values for each printer and compare the number of minutes when the number of photos is 120.

Multiply each ratio by 120, then subtract the results.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
