Answer:
x = -1
Step-by-step explanation:
4(x - 7) + 8(1 - 6x) = 24
distribute
4x - 28 +8 -48x = 24
Combine like terms
-44x -20 = 24
Add 20 to each side
-44x -20+20 = 24+20
-44x = 44
Divide each side by -44
-44x/-44 = 44/-44
x = -1

Answer:
the desired equation is 4x - y = -10
Step-by-step explanation:
Recall that parallel lines have the same slope.
A quick trick for finding this new equation is to adapt the given equation 4x - y = 2. Replace that constant 2 with the constant C, and substitute -2 for x and 3 for y:
Our 4x - y = 2 becomes 4(-2) - (2) = C, and -8 -2 = C, or C = -10.
Then the desired equation is 4x - y = -10
Answer:
441
Step-by-step explanation:
Use a proportion.
756 miles is to 12 hours as x miles is to 7 hours
756/12 = x/7
12x = 7 * 756
12x = 5292
x = 441
Answer: 441 miles
