The upper left choice is the only one that has the absolute value right.
Answer:
-5b+5x+12
Step-by-step explanation:
x + (x + 2) + (x + 4) = 384
2x + 2 + (x + 4) = 384
3x + 6 = 384
3x = 378
x = 126
The answer is 126.
There are 4 quarts in a gallon. 4 times 5 is 20 and 28 divided by 20 is 1.4. So the cost of one quart of the oil is $1.40
4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
