You can get this my multiplying the scale factor by the height. In this case you need to use the bottom number to multiply since you are going in reverse.
They met after a/(x/20) = (3/5x)/(x/20) = 12 mins.
Answer:
1. 1 3/8, 2 1/4, 2 1/2, 2 7/8, 3 1/8, 3 1/4
2. 12
3. 1 7/8
4. 5 3/4
5. 4 5/8
1) we have to subtract by the number 18p from each of your sides
Like: 10p + 5 - 18p
= 18p -3 -180
This gives us: -8p + 5 = -3
Nextly, we have to subtract by 5 on each of your sides
Like: -8p + 5 - 5
= -3 - 5
This gives us: -8p = -8
Now we have divide by the -8 on each of your sides:
Like: -8p ÷ -8
= -8 ÷ -8
Answer: p = 1
I hope it helped you:)
