Answer:
10 miles
Step-by-step explanation:
Find how much she runs during one track practice by dividing 8 by 4. This gives you the equation 2x, with x being the number of track practices.
On the right side, there are
• 2•2 = 4 atoms of Nb
• 2•5 = 10 atoms of O
so among the reactants on the left, the reaction is balanced as
4 Nb + 5 O₂ → 2 Nb₂O₅
Answer:
9) y = -x + 5
10) y = -7/2x - 5
11) y = x - 1
12) y = -5x/3 - 3
13) y = -4x/1
I'm not 100% sure for some of these answers since the pic is a bit blurry, but they're pretty accurate.
