Old price = 2400
new price = 2040
difference = 2400 - 2040 = 360
difference divided by old price = 360 / 2400 = .15
that is the rate of the difference.
300x250
Answer: chans
Step-by-step explanation:
-2(a - 8) + 6a = 36
-2(a) + 2(8) + 6a = 36
-2a + 16 + 6a = 36
-2a + 6a + 16 = 36
4a + 16 = 36
- 16 - 16
4a = 20
4 4
a = 5
Answer:
Step-by-step explanation:
plug in both values and see if the equations are true
1.5 = 1(1) + 5
1.5 = 1 + 5
1.5 does not equal 6
so (1,1.5) is not a solution
4 = 1(12) + 5
4 = 12 + 5
4 does not equal 17
so (12,4) is not a solution
