Answer:no solution the lines are parallel they have the same slope
Step-by-step explanation:
8x+2y=14
-8x. -8x
2y= -8x+14
Divide all by 2
Y= -4x +7
8x+2y=4
-8x. -8x
2y= -8x+4
Divide by 2
Y-= -4x+2
Since they both have -4x they have the same slope they never touch making them parallel
You just put the scale of one building on one side and the scale of the similar building on other side, with width and length written in same place (denominator or numerator). With x for the part that you dont know
Length of one building / width of one building = length of other building / width of other building
12 / 9 = 100 / x
Solve for x, by cross-multiplying
12 * x = 100 * 9
12x = 900
X = 900/12
X = 75 ft
Answer:
456 is the number you are looking for.
Step-by-step explanation:
Consecutive numbers are numbers which continuously follow each other in the order from smallest to largest.
Have a nice day!
Since there is no repetition allowed, there are 10 possibilities for the 1st digit, 9 for the 2nd, 8 for the 3rd, and 7 for the 4th. This gives a total of (10)(9)(8)(7) = 5040 four-digit codes.
For all odd digits to be used, there are 5 possibilities for the 1st digit (1,3,5,7,9), 4 for the 2nd, 3 for the 3rd, 2 for the 4th. This gives a total of (5)(4)(3)(2) = 120 codes that only use odd digits.
Therefore there are 5040 - 120 = 4920 codes that do not consist of all odd digits. The probability is 4920/5040 = 41/42.
