Answer:
.8
Step-by-step explanation:
5 red marbles, 2 Green marbles and 3 black marbles = 10 marbles
P (red or black) = number of red or black/ total
= (5+3)/10
=8/10
decimal form = .8
205 - d = 160
Add d to both sides of the equation
205 = 160 + d
Subtract 160 from each side
45 = d

Hi there!
I do not know the other values of the pay check, so I will explain to you how to solve for 40% of the 270 dollars. To solve, we'll need to set up a proportion. That proportion is 40/100 = x/270. Next, we need to cross-multiply: 100x = 10800. Lastly, we'll divide to figure out what 40% of 270 is. x = 108.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
