Answer:
Solution= x=1/3k-y-z
Step-by-step explanation:
Answer:
Step-by-step explanation:
3x+3y+3z=k ---> 3x=-3y=3z+k
Move the variables to the right
3x=-3y-3z+k ---> x=-y-z+1/3k
Divide both sides by 3
x=-y-z+1/3k ---> x=1/3k-y-z
Use the communicative property to reorder the terms
Solution= x=1/3k-y-z
Answer:
5100 cm of wax will make 17 candles
Step-by-step explanation:
Each candle is 5 cm long, 4 cm wide, and 15 cm tall
to know the space they cover, we divide it with their volume and since they are in rectangular prism
Volume is length x width x height
5 x 4 x 15 = 20 x 15 = 300cm
1 candle = 300cm
what number of candle is represented as x
1 candle comprises of 300cm wax
x = 5100
300x = 5100 x 1 =5100
300x= 5100
x= 5100/300 = 17
5100 cm of wax will make 17 candles
Answer:
x=6
Step-by-step explanation:
(0.6)(x-1.5)=2.7
(x-1.5)=4.5
x=6
The answer is equal, or the same, because if two lines have the same slope then they will never touch, which is what parallel lines are. I hope this helps!
Answer:
Step-by-step explanation:
Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...
x + (x+40) = 1180
2x = 1140 . . . . subtract 40
x = 570 . . . . . .divide by 2
x+40 = 610 . . . . the speed of the faster plane
The two speeds are 570 mph and 610 mph.
