Ok here is how you do this:
you need to replace y with 20 and then solve to find x, i.e. solve this equation
20=2/5x
1. Simplify 2/5x to 2x/5
20=2x/5
2. Multiply both sides by 5
20 * 5=2x
3. Simplify 20 * 5 to 100
100=2x
4. Divide both sides by 2
100/2=x
5. Simplify 100/2 to 50
50=x
6. Switch sides
x=50
so your answer is B. 50
I hope this helped!
Answer:
1:00 am
Step-by-step explanation: if it is 11:00 add the 5 hours because NYC is 5 hours behind London so when you add them you get to 4:00 am then since Rio is three hours behind you subtract 3 hours from 4:00 am and you get 1:00 am.
I got -12.9315 , idk if that's right , I just used my calculator
Plot the points you found in part (b) on a suitable set of coordinates and draw a line through them. It might help your accuracy to use the y-intercept of 20 also.
