Answer:
<u>Temperature of the ice for ice-skating = -5 °C</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Temperature of the ice for an ice hockey match = - 7 °C
Temperature for ice- skating is 2 degrees warmer.
2. What is the temperature of the ice for ice-skating?
For the correct calculation, we use this formula:
Temperature for ice-skating = Temperature of the ice for a hockey match + 2
Temperature for ice-skating = -7 + 2
<u>Temperature of the ice for ice-skating = -5 °C</u>
We add 2 to the temperature of the ice for a hockey match because the temperature for ice-skating is described as warmer. If it were described as colder, we should subtract.
There is a 20.2 percent chance he will get at least one cola
3 less than twice a number x.
Twice a number would be the x multiplied by 2, and 3 less would be 3 subtracted by 2*x.
2x-3 <- The numeral form.
I hope this helps!
