Answer:
y = 4/5x - 9/5
Step-by-step explanation:
4x - 5y = 9 to solve for y you get it by itself.
-4x -4x minus 4x from both sides
-5y = - 4x + 9
/-5 /-5 Divide both sides by 5
y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5
-2.6b + 4 = 0.9b - 17
<u>+2.6b </u> <u>+2.6b </u>
4 = 3.5b -17
<u> +17 </u> <u> +17 </u>
21 = 3.5b
6 = b
Answer: b = 6
The newer would be 33 days because you would find the lowest common multiple that matches both of the numbers.
11, 22, 33
3,6,9,12,15,18,21,24,27,30,33
