Answer:
(2b - 5) + b + (b + 80) = 983
Step-by-step explanation:
Given that,
Total score of three teams = 983
Since the teams' scores are given in reference to team B's score, let 'b' be the score of team B.
So,
The scores of Team A = (2 * b) - 5
The scores of Team B = b
The scores of Team C = (b + 80)
Thus,
The equation for determining the total points of Team B would be:
(2b - 5) + b + (b + 80) = 983
On solving,
(2b - 5) + b + (b + 80) = 983
⇒ 2b + b + b = 983 + 5 - 80
⇒ 4b = 908
⇒ b = 908 ÷ 4
⇒ b = 227
Team B's score = 227
Team A's score = (2 * 227 - 5)
= 449
Team C's score = 227 + 80
= 307
Total ⇒ 449 + 227 + 307 = 983
Hence proved.

Answer:
an = 9n -16
Step-by-step explanation:
First find the common difference, d
Take the second term and subtract the first
2 - (-7) = 2+7 = 9
We are adding 9 each time
Check 2+9 =11, check 11+9 = 20 check
The first term in the sequence is a1 so a1 =-7
an = a1 + d(n-1)
an = -7 + 9(n-1)
Distribute
an = -7 +9n-9
Combine like terms
an = 9n -16
Answer:
Blue: 13/100 = 0.13 = 13%
Purple: 130/100=1.3=130%
Step-by-step explanation:
The picture shows 100 cubes in a grid that's 10 by 10. This means the shaded amount is a number out of 100. The first is 13 out of 100 which converts to 0.13 and 13%. The second has all the cubes shaded which means 100/100 which is 1 or 100% plus the last has 30 cubes out of 100 which converts to 0.30 or 30%. Together this makes 130/100 or 1.30 or 130%.
