Since Bonnie was 10 last year, we can assume that Bonnie is 11 this year.
As we know there is an 8 year difference between Bonnie and her brother, we do:
11 - 8 which gives us 3.
Bonnies brother is 3 years old!
Answer:
$10.50
Step-by-step explanation:
4+3=7
12.25/7=1.75
6x1.75=10.50
R+s-t-(r-s+t)
=2s-t is the answer
People think this answer would be just =2s but I have verified with an online calculator and the answer that textbooks look for regarding this is 2s-t
You would assume you would go r-r and thats 0 so no r's
you would say s-(-s) makes it plus and theres 2s
and you would say -t -(+t) is -t
that's why the answer is 2s-t
At first I also did t-(+t) and thought it would be no t's but the answer is in fact 2s-t
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.
