Answer:
D)
Step-by-step explanation:
First we have to subtract 5 from both sides

Now, square both sides

x - 6 = 49
Now, add 6 to both sides
x - 6 +6 = 49 + 6
x = 55
Common difference of the arithmetic sequence, is


Twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
SI = PRT /100
1. SI = 400*5*1/100
= 2000/100
= $ 20
2. SI = 1000*8.5*3/100
= 25.5*1000/100
= $ 255
3. SI = 200*9*1/2*100
= 900/100
= $9
4. SI = 20000*12*3/100
= 200*12*3
= 7200
5. SI = 1200*4.5*6/12*100
= 4.5*6
= $27
Amount to pay = Principal + SI
= 1200+27
= $1227 ( But this answer isn't there in the options )
