ANSWER: 60 female lions
In the ratio there are 21 male lions and 20 female lions, in total 41 lions. Create a proportion relating the total number of lions in the ratio (41) and in the problem (123), and the number of female lions in the ratio (20) and in the problem (unknown).
20/41 = x/123
Cross multiply and solve
20(123)=41x
2460=41x
60=x
You just multiply 16 and 3 and it gives you 58
Answer:
x = -4
Step-by-step explanation:
2x + 34 = 6 - 5x
Subtract 34 from both sides.
2x = -28 - 5x
Add 5x to both sides.
7x = -28
Divide both sides by 7.
x = -4
Proof:
2x + 34 = 6 - 5x
Substitute variable.
2(-4) + 34 = 6 - 5(-4)
Multiply.
-8 + 34 = 6 + 20
Add.
26 = 26
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 ~~
