8 times the difference between a number and 6 is equal to 4 times the number.
1 answer:
Answer:
The variable titled "the number" is A: 12.
Step-by-step explanation:
The problem is 8 * (x - 6) = 4 * x
Try the first number as x and rewrite the expression.
8 * (12 - 6) = 4 * 12
Following PEMDAS (the Order of Operations), you need to solve the problem inside the parenthesis.
12 - 6 = 6
Rewrite the problem.
8 * 6 = 4 * 12
8 times 6 is 48.
4 times 12 is 48.
The variable in the expression 8 * (x - 6) = 4 * x is 12.

"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.
If 4 students are competing, then the race has
4! = 4 • 3 • 2 • 1 = 24
possible outcomes.
Answer:
the best equation would be A-99=n
Step-by-step explanation:
x=3/2-1/4
8x+2y=12
move the variable to the right side and change the sign.
8x=12-2y
divide both sides of the equation by 8
x=3/2-1/4y
the final solution is
x=3/2-1/4y
