Step-by-step explanation:
Here Given
Total counters = 81
red counters are 9 more than the yellow ones.
And Yellow counter = blue counter
So let the Yellow counter be x and as blue counter and yellow counter are same then blue counter will be also x
And by the question
Red counter = 9 + x
Now
9 + x + x + x = 81
9 + 3x = 81
3x = 81 - 9
3x = 72
x = 72 / 3
Therefore x = 24
Now
Red counters = 9 + 24 = 33
Blue counters = 24
Yellow counters = 24
Hope it helped :)
You can use Guess and Check and divide the 50 pounds into 2 parts. Multiply the price for both and do square root for the prices. Then at the 2 square roots and see if they add up to $6.40. If not, then divide the 50 pounds into something else, like 30 and 20 or something like that.
Answer:
6T + p
6T + p = 27
T = 4 ; p = 4
Step-by-step explanation:
Given the following :
Points awarded for touchdown = 6 and then try for a point 'p' after touchdown
Hence, number of points scored on
touchdowns T and points after touchdowns p by one team in a game.
6points * number of touch downs (T) + point 'p' after touchdown
= 6T + p
B) If a team wins a football game 27-0,
Possible number of touch downs and points after touchdown :
Then 6T + p = 27
27 / 6 = 4 remainder 3
Hence, possible number of touch downs = 4
Number of points p = 27 - (6*4) = 27 - 24 = 3
C.) if winning = 21-7
Team A = 21
Hence, T = 21/6 = 3 remainder 3
T = 3 ; p = 3
Team B = 7
T = 7/6 = 1 remainder 3
T = 1 ; p = 1
Hence,
Total for both teams :
T = (1 + 3) = 4
p = (3 + 1) = 4
