5a – 10b = 45, when b = 3
balandron [24]


Well, since you have the value of b, the first thing you want to do is substitute that value in for b.

5a - 10(3) = 45

10*3 = 30

5a - 30 = 45

Now, to get the variable by itself (a) you have to + 30 because you have to reverse the subtraction.

5a = 75

Now, you divide by 5 to finish getting a by itself.

a = 15

Hope this helps!

Could you tell me how to display this in a graph please I’m sorry I could only give 10 points but I will answer a question if yo
Ratling [72]

I’m not sure on this one but what I think you need to graph is the different floors on the Y axis and the time on the X axis. For the time, label it as 1 minute, 1m 30 secs, 2 mins, 2 mins 30 secs and so on. Then you can plot the points. Don’t take my word for this one because I’m not too familiar with these. Sorry I couldn’t be as helpful ~~
