Answer:
A: 253125 per game
B: 5273 per minute
C: 9375 per minute
Step-by-step explanation:
For A you just divide 20250000/80
For B you just use the number you got when you divided in question A which is 253125 and divide it by 48.
For C 2/3 of every game is 27 minutes so just divide 253125/27 which is 9375 (i believe this is right im not sure)
Let
x = the number of a-cables
y = the number of b-cables
z = the number of c-cables
Cable a uses 3 black, 3 white and 2 red wires.
Cable b uses 1 black, 2 white and 1 red wire.
Cable c uses 2 black, 1 white and 2 red wires.
Because 120 black, 110 white and 100 red wires were used, therefore the system of equations is
3x + y + 2z = 120 (1)
3x + 2y + z = 110 (2)
2x + y + 2z = 100 (3)
Answer:
3x + y + 2z = 120
3x + 2y + z = 110
2x + y + 2z = 100
where
x,y,z = the number of a, b and c-cables respectively.
Answer:
{n*(n+1) } /2
Step-by-step explanation:
The clearest pattern is that the last digit is multiplied by the number after it and then the multiplication is divided by 2.
1 is multiplied by 2, then divided by 2.
2 is multiplied by 3, then divided by 2.
3 is multiplied by 4, then divided by 2.
So, the pattern is:
{n*(n+1) }/2.
Hope this helped!
3a- 2b + 8b - 2 + 6a + 3c
3a + 6a -2b +8b + 3c - 2
9a + 6b + 3c - 2
Another number that could be in the pattern is the number 8
