There are a couple of ways to write this. One, the simplest in my opinion, is this:
Five wholes and 96 hundredths. To write this it is:
5 96/100
However, this can be simplified and we know this because their GCF (greatest common factor) is 4. Divide each by 4.
= 24/25
(NOTE: DONT SIMPLIFY THE WHOLE NUMBER!)
check the picture below.
so, when we have a line from a 90° angle running perpendicular to the opposite side, like in this case, we end up with three similar triangles, a large one containing the other two, a medium and a small one.
now, using the sides proportions as you see there, of the small and large one, we get that much.
Im thinking it's false. 18 isn't even between 4 and 9.
1. The two equations follow the slope-intercept form which y=mx + b. They have the same y-intercept which is equal to 900.
2. Suppose x= 10
Plan Alpha: y=-7x+900=-7(10)+900=830
Plan Foxtrot: y = -17x+900 = -17(10)+900=730
Between the 2 plans, the lower value is 730. Plan Foxtrot is better for reduction of pollution.
3. The city council should choose Plan Foxtrot because the reduction of pollution is much greater. Their goal would be reached faster if they go with faster reduction of pollution.
10 + 6n = 4 - 4n
I'm just guessing but I'm pretty sure that's it.
