Answer:
x= 13/22
Step-by-step explanation:
you can substitute y= 34 x on the second equation
34x = -54x +52 add 54x to both sides
34x +54x = -54x +54x +52
88x = 52 divide both side by 4
22x = 13 divide both sides by 22
x= 13/22
Answer:
x = -2
Step-by-step explanation:
The x coordinate of the midpoint is found by adding the x coordinates together and dividing by 2
( -4+0)/2 = -4/2 = -2
The y coordinate of the midpoint is found by adding the y coordinates together and dividing by 2
( 8+10)/2 = 18/2 = 9
Mercury the liquid metal? 674.1°F or 356.7°C
Answer:
x = 12
Step-by-step explanation:
Solve for x:
(5 x)/6 + 4 = x + 2
Put each term in (5 x)/6 + 4 over the common denominator 6: (5 x)/6 + 4 = (5 x)/6 + 24/6:
(5 x)/6 + 24/6 = x + 2
(5 x)/6 + 24/6 = (5 x + 24)/6:
(5 x + 24)/6 = x + 2
Multiply both sides by 6:
(6 (5 x + 24))/6 = 6 (x + 2)
(6 (5 x + 24))/6 = 6/6×(5 x + 24) = 5 x + 24:
5 x + 24 = 6 (x + 2)
Expand out terms of the right hand side:
5 x + 24 = 6 x + 12
Subtract 6 x from both sides:
(5 x - 6 x) + 24 = (6 x - 6 x) + 12
5 x - 6 x = -x:
-x + 24 = (6 x - 6 x) + 12
6 x - 6 x = 0:
24 - x = 12
Subtract 24 from both sides:
(24 - 24) - x = 12 - 24
24 - 24 = 0:
-x = 12 - 24
12 - 24 = -12:
-x = -12
Multiply both sides of -x = -12 by -1:
(-x)/(-1) = 12
(-1)/(-1) = 1:
Answer: x = 12
