Answer:
y = 4
x = -6
Step-by-step explanation:
multiply first equation by 3
3×(5x+4y)= -14 ➡ 15x + 12y = -42
multiply second equation by -5
-5×(3x+6y)= 6➡ -15x -30y = -30
now add both equations up
15x +12y -15x -30y = -42 -30 (15x will eliminate -15x)
-18y = -72
y = 4 use this to find value of x
3x + 6×4 = 6 ➡ ex = -18 ➡ x = -6
Answer:
14 liters
Step-by-step explanation:
10 liters : 4 liters of juice and 6 liters of water
4/10 of juice and 6/10 of water
make it to 70% of juice and 30% of water
add 14 liters of juice
14/20=70% of juice
6/20=30% of water
The third one since you can interpret the first column of the graph as the x coordinates and the second column as the y coordinate.
Answer:
x = 25
Step-by-step explanation:
0 = 2x - 50
0 - 2x = -50
-2x = -50
x = 25
Answer:
probability of winning is
Step-by-step explanation:
As it is given , 4 cards are available, there are 4! mean total possible way of ordering is 24
following are the cases of loosing
1) first card is fire.
Thus there are 3! = mean 6 possible ways for particular ordering to occur.
2) If wind is first card and Fire is second. Then, There are 2! = 2 ways to occur.
Hence, the probabiIity of losing is given as 
therefore probality of winning is 
probality of winning is
