Answer:
Step-by-step explanation:
Given that,
y = x + 6 equation 1
3x - 3y = -18. Equation 2
Substitute equation 1 into equation 2
3x-3(x+6) = -18
3x - 3x - 18 = -18
-18 = -18
Therefore, it has no solution. Check attachment for echelon matrix solution
B. y = -2x + 5 equation 1
2x + y = -7. Equation 2
Substitute equation 1 into 2
2x -2x + 5 = -7
5 = -7
Since the equation is not balance, then, it has infinite numbers of solution.
C. y = -4x + 11. Equation 1
6x + y = 11. Equation 2
Substitute equation 1 into 2
6x - 4x + 11 = 11
2x = 11 - 11
2x = 0
x = 0
Also, y = -4x + 11
y = 0 + 11 = 11
Then, this has a unique solution I.e. one solution.
Answer=28 players
If there are 4 players at every 1 table then...
1 table would have 4 players
4=4
2 tables would have 8 players
4+4=8
3 tables would have 12 players
4+4+4=12
4 tables would have 16 players
4+4+4+4=16
5 tables would have 20 players
4+4+4+4+4=20
6 tables would have 24 players
4+4+4+4+4+4=24
7 tables would have 28 players
4+4+4+4+4+4+4=28
____________________________
You can also solver this problem by multiplying the number of tables, 7, by the number of player per table, 4.
7*4=28players
Answer:
Leslie should buy her dog food from Petsmart because the price per can is cheaper
Step-by-step explanation:
Step one;
given data
At Petco, we are told that she receives 9 packs with four cans each for $25
Hence Petco gives a total of 9*4= 36cans
the cost of each can will be 25/36
=$0.69 per can
Step two:
At Petsmart, we are told that she receives 7 packs with six cans each for $25
Hence Petsmart gives a total of 7*6= 42cans
the cost of each can will be 25/42
=$0.59 per can
<u>Leslie should buy her dog food from Petsmart because the price per can is cheaper </u>
