The unknown is 2% and sorry
Answer:
26 units
Step-by-step explanation:
Due to:
in the rect line, left to zero = 13 (absolute value)
in the rect line, right to zero = 13 (absolute value)
So the sum of each absolute value is the distance.
Best regards
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
Step-by-step explanation:
-20+11
negative and positive sign will change in negative so ans will be=-9
because positive sign is on greater number
