Answer:
1 1/2 miles
Step-by-step explanation:
if running 1 lap around a track is 1/2 miles then all we have to do is add it up
so we know that 1/2 miles is one lap
so if he runs two laps we would have run 1 mile
now that we know that he would have ran 1 mile in 2 laps then all we have to do it just add 1 more 1/2 mile in which would give u the answer of 1 1/2 miles or 1.5 miles
Easiest method solving 2 unknowns is Substitution.
So there will normally be 2(ormore)equations given.
Say
X+Y= a
bX=cY + d
a b c d are numbers they give
So first we rearrange the first equation
X = a - Y
No we substitute this into the 2nd equation so that we can get Y
since we know X = a-Y,
b(a-Y) = cY + d
we rearrange and we can find Y for this, it is just Y and numbers
hence finding Y, we sub the value for Y into X = a-Y and we get X also .

Answer:
3rd
Step-by-step explanation:
The degree is the highest exponent that the polynomial has.
This one has a 3, 2, 1, and 0 degree, and out of those 3 is the largest, so we know the overall degree is 3rd degree.
