Answer:
12
Step-by-step explanation:
X/x-2 >= 0 equals x/x >= 0+2 simplified x >=2
Woah this looks really hard... I’m sorry if someone doesn’t answer try searching it up
Answer:
- Considering the temperature is 0°C and
- It is changing at a rate of -3 per hour.
So, it took 11 hours for the change in temperature to be -33.
Step-by-step explanation:
Rate of change basically means the amount of change to how long it takes for the change to occur.
Rate of change = Change in Value/ Change in time
On a certain day the temperature changed at a rate of -3 per hour.
Let suppose the Temperature at 8:00 = 0°C
As the temperature changed at a rate of -3 per hour.
It means the Temperature at 9:00 = -3°C.
so
Rate of change = (-3 - 0)/(9:00 - 8:00) = -3°C per hour
So, the temperature to be -33°C, it would take 11 hour as -3 × 11 = -33.
Therefore, it took 11 hours for the change in temperature to be -33.
Answer:
![15x\leq 125](https://tex.z-dn.net/?f=15x%5Cleq%20125)
8 calculators at most.
Step-by-step explanation:
Let x represent number of calculators.
We have been given that each calculator costs $15. So the cost of x calculators would be
dollars.
Since the order must be less than $125 in order to not go over budget, so cost of x calculators should be less than or equal to 125. We can represent this information in an inequality as:
![15x\leq 125](https://tex.z-dn.net/?f=15x%5Cleq%20125)
Therefore, our required inequality would be
.
Let us divide both sides of inequality by 15 as:
![\frac{15x}{15}\leq \frac{125}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B15x%7D%7B15%7D%5Cleq%20%5Cfrac%7B125%7D%7B15%7D)
![x\leq8.3333](https://tex.z-dn.net/?f=x%5Cleq8.3333)
Since we cannot order 0.33 of a calculator, therefore, the math club can order 8 calculators at most.
