Answer:
8?
Step-by-step explanation:
250/5 = 50
therefore they must wash at least 50 cars
We see all of them have 2 and 0.5
so therfor b+c=-2.5
so
remember
a(b+c)=ab+ac
so
8.6(-2-0.5)=8.6(-2)+8.6(-0.5)
last option
Answer:
( 5 - 2t ) < - 4
Step-by-step explanation:
The midnight temperature is 5 °C and the temperature is decreasing at the rate of 2°C per hour.
If t is the hours past midnight then after t hours the temperature will be ( 5 - 2t ).
Now, if this temperature is colder than - 4° C, then the inequality can be written as ( 5 - 2t ) < - 4 (Answer)
