Answer:
39 athletes
Step-by-step explanation:
There is a total of 45 people on the bus. This INCLUDES the athletes (A), 2 coaches and 4 managers.
Therefore, we need to sum A, 2 and 4 and equal it to 45:
2 + 4 + A = 45 so we need to used equation d.
To calculate how many athletes are on the bus, find the value of A:
2 + 4 + A = 45
Subtract 2 from both sides: 4 + A = 43
Subtract 4 from both sides: A = 39
Answer:
6. x = 2
7. 35721
Step-by-step explanation:
<h3><u>Question 6</u></h3>
Given equation:






Add 1 to both sides:


Divide both sides by 2:


Therefore, x = 2.
<h3><u /></h3><h3><u>Question 7</u></h3>
Given identity:

To find the square of 189, rewrite 189 as (200 - 11).
Therefore, a = 200 and b = 11.
Substitute these values into the given identity and solve:

Gerard is correct. I don't know how to explain but he just is. Hope this helps :)
