The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months
Answer: 5th degree trinomial
The degree is 5 because its the largest exponent of the single variable polynomial.
It's a trinomial because there are 3 terms. The terms are separated by a plus or a minus.
14 / 45
56 / 100 reduces to 14 / 45
Step-by-step explanation:
3p−5>2p+p−7
3p−5>3p−7
3p−5−3p>3p−7−3p
−5>−7
−5+5>−7+5
0>−2
