The answers for this question are 2 , 3 , and 5. these 3 make the most sense.
Answer:
The number is -3.
Step-by-step explanation:
Set up an equation:
Variable n = number
12 + 7n = n - 6
Assuming the question is solve for n, isolate the variable:
Subtract n from both sides:
12 + 6n = -6
Subtract 12 from both sides:
6n = -18
Divide by 6 on both sides:
n = -3
Check your work:
12 + 7(-3) = -3 - 6
12 - 21 = -3 - 6
-9 = -9
Correct
Answer:
$48.30
Step-by-step explanation:
If the dinner was $42.00 and they wanted to give a 15% tip, then to find that start by multiplying 42 by 0.15
42.00 x 0.15 = 6.3
now add $6.30 to $42.00
42 + 6.3 = 48.3
Answer
Step-by-step explanation:
I am not an artist so
First, we know the formula to find the area of a square is A=s^2 where s= side length. Since we have the area, we can solve for s: 81=s^2. To solve for s, you would take the square root of both sides to get s=9. Then, we know the formula for the perimeter of a square is P=s*4. Since we now have s, we can solve for P: P=9*4 or P=36 feet which is the final answer.
