Answer:
Step-by-step explanation:
<u>Given work on simplification</u>
- (6 and one-half + 2 and three-fourths) minus 1.5 times (4.5 divided by 0.5)
- (6 1/2 + 2 3/4) - 1.5 (4.5 ÷ 0.5)
<u>Step 1</u> 9 and one-fourth minus 1.5 times (4.5 divided by 0.5)
- 9 1/4 - 1.5 (4.5 ÷ 0.5)
- This is ok as first step is solving parenthesis
<u>Step 2</u> 7.75 times (4.5 divided by 0.5)
- 7.75 (4.5 ÷ 0.5)
- Incorrect, subtraction should be the last step
Answer: second step.
Step-by-step explanation:
you then have to distribute the answer not subtract 9 1/4 from 1.5
you have to do the parenthesis next
4.5/0.5=45/5=9
then
1.5*9= 13.5
then
9.25-13.5 which I think you are capable of solving

Answer:
19 players
Step-by-step explanation:
The total being spent is ...
bus cost + (per player cost) × (number of players) = total raised
250 + 25.85p = 741.15
25.85p = 491.15
p = 491.15/25.85 = 19
The team could bring 19 players to the tournament.
