1. You have to make a system of equations.
2. The problem gives the following information:
- <span>. Emi said wow I think the top of that waterfall is about 20 ft more than three times the height of a young Redwood.
- Margaret had a different opinion she said no I think it's about 50 ft less than 4 times the height of the Redwood.
3. So, you have:
y: the height of the waterfall.
x: </span>the height of the Redwood
4. The equations are:
y=3x+20 (i)
y=4x-50 (ii)
3x+20=4x-50
x=70 ft
y=3x+20
y=230 ft
H<span>ow tall is the Redwood and how high is the waterfall?
</span>
The Redwood: 70 ft
The waterfall: 230 ft
2(t + 5) > 4t - 7(t + 3)
2t + 10 > 4t - 7t - 21
2t + 10 > -3t - 21
2t + 3t > -21 - 10
5t > -31
t > -31/5
To work out what percent of 60 is 150 just do the following:
150 / 60 = 2.5
2.5 x 100 = 250
Therefore 150 is 250% of 60. Hope I helped!

This material should not be too difficult. Please study more. :)
Uhh that would be to much but I'm pretty sure if you download the app photo math and scan the question it will show you the slopes.
