Answer:
-13
Step-by-step explanation:
Given that:
Average temperature for a period of 4 days = - 8
Average temperature for a 5 day period = - 9
Temperature on the 5th day:
(total temp for the 4 days + 5th day temperature) / 5 = - 9
Let 5th day temperature = x
Total temperature for the 4 days = 4 * - 8 = - 32
(-32 + x) / 5 = - 9
-32 + x = - 45
x = - 45 + 32
x = - 13
Answer:
a. 0.9 miles
b. 0.54 miles
c. 1.44 miles
Step-by-step explanation:
The answer should be D because it only crosses Y at -8 and doesn't cross X
Answer:
11 trips on the toll road can be represented by replacing the variable t with 11:
A(11) = 224 - 14(11)
A(11) = 224 - 154
A(11) = 70 dollars.
You can solve for Nicole's account being empty by setting y equal to 0 (how much money she has left):
0 = 224 - 14t
14t = 224
t = 224/14
t = 16 trips on the toll road before Nicole runs out of money.
