Answer:
2(n + 3) - 6 is the expression that represents the final number.
Step-by-step explanation:
Answer: the expression becomes 2(x +3) - 6.
Let the number be x. Then according to the question,
Step 1 :- Adding 3
=> x + 3
Step 2 :- Multiply the sum by 2
=> 2×(x + 3)
Step 3 :- Subtract 6
=> 2(x +3) - 6
Thus the expression becomes 2(x +3) - 6.
$17 and 2 hours
$85 and 10 hours
$170 and 20 hours
55 =x
x+15=2x-40
Subtract x from each side
x-x+15=2x-x-40
15 = x-40
Add 40 to each side
15+40 = x-40+40
