Step-by-step explanation:
-2x+3=-4
-2x=-7
x=7/2=3.5..
HOPE IT HELPS.
From total of 10000 programs only one is winning. The probability that you will get the winning number can be calculated as the ratio between the numbers of desired events and the total numbers of events. There is only one winning number , so the ratio is : 1/10000. If you purchase two programs the probability is the sum of the two probabilities: 1/10000+1/10000=2/10000.
Use Pythagorean theorem
A^2 + B^2 = C^2
12^2 + B^2 = 15^2
Solves for b
-5/7 - (-6/7)z < -2/7
-5/7 + 6/7z < -2/7
6/7z = -2/7 + 5/7 = 3/7
z = 3/7 / 6/7 = 3/7 x 7/6 = 3/6 = 0.5
z = 0.5
so
so at the same weight, the 5 pounder costs 1 cent more
