Answer:
6 pictures
Step-by-step explanation:
Let x be the number of pictures that was bought
Let y be the total amount of money collected for the picture
y= 3.25+12.75
3.25+12.75x= 79.75
Therefore x can be calculated as follows
12.75x= 79.75-3.25
12.75x= 76.5
x= 76.5/12.75
= 6
Hence Joshua ordered 6 pictures
y=-5x
take two points, I took 0,4 and 1-,1 and do
y2-y1 over x2-x1
Answer:16288.xy
a
12 is your answer
12 x 1 = 12
12 x 5 = 60
hope this helps
