Sum = 1st term added to the last term & multiplied by half the number of terms
S = (a+l)n/2

Which equations represent functions? 2x+3y=10. 4x=16. 2x - 3 =14. 3y=18. 14.6=2x
Vlad [161]
2x + 3y = 10 -> y = -2/3x + 10/3 it's a function

4x = 16 -> x =4 it's not a function

2x - 3 = 14 -> x = 8.5 it's not a function

3y = 18 -> y = 6 it's a function

2x = 6 -> x = 3 it's not a function

koban [17]

Answer:  No two students ran same distance

Step-by-step explanation:

Given

Stacy ran \frac{9}{12} of a km i.e.

\Rightarrow 1\times \dfrac{9}{12}=\dfrac{3}{4}=0.75\ km

Jules ran \frac{4}{5} of a km i.e.

\Rightarrow 1\times \dfrac{4}{5}=0.8\ km

Raul ran \frac{3}{4} of mile i.e.

\Rightarrow 1\times \dfrac{3}{4}=0.75\ miles\\\\\text{1 mile=1.6 km}\\\\\Rightarrow 0.75\ miles=1.2\ km

So, no two students ran the same distance.
