Answer:
-1/3
Step-by-step explanation:
formula is y2-y1/x2-x1 -> 3-2/1-4 -> 1/-3 -> -1/3
If you spent 80% that means you have 20% left, we'll use B as variable
20% x B = 12
0.20/0.20 x B = 12/0.20
B = 60
15 times 6 = 90, 7 times 8 = 56, 9 times 3 = 37 or all of them together equals 153 :)
10/3. To find this answer you have to either multiply or divide by a specific number. You choose the number that goes into each of them. In this case I divided by 2 to both the top and bottom number. When I did this I got the answer of 10/3
