John's car was worth $16,000. After 5 years, the value of the car decreased to $10,000. What was the average decrease in value per year?
-$12,001
(10,000- 16,000)/ 5
10,000- 16,000 = -6,000
-6,000/ 5
True or false:
-13 - 12 will have a negative result
true
Keep, switch, switch: -13 + -12 = -25
simplify:
16-20
-4
subtract, then the bigger # gets the sign
(-5)3
-125
simplify:
33-(-16-5)/ -6+2
-12
1) parathesis (-16-5)= -21
2) exponent 33= 3x3x3= 27
3) subtract 27- (-21) keep switch switch= 48
Denominator
1) -6 +2= -4
Now divide 48/ -4
3,518 ft
6,825- 3,325 + 18
-80
-19
step 1: keep switch, switch
step 2: different signs= subtract
step 3: the bigger # gets the sign

Springfield is 12 miles east and 4 miles north of Bristol. Franklin is 7 miles west and 6 miles south of Springfield. If the tree cities are mapped on a coordinate plane with Bristol at the origin, give the location of each city as an ordered pair.
Bristol (0,0)
Springfield (12, 4)
Franklin (5, -2)
the zero will be the first number will result in a 0 but if the second number is 0 it will be undefined
