$24.50 is your original amount, and you know you have a 20% added to that. So, you can multiply the money by the percentage:
24.5 x 1.2 (we multiply it by 1.2 because we want the tip PLUS the original amount)
= 29.4
So the answer is the first choice, $29.40
Answer:
( 3x + 5 ) ( x - 4 )
Step-by-step explanation:
1.) Factors of 20 = (1,20) (2,10) and (4,5)
2.) ( 3x + 5 ) ( x - 4 )
3.) 3x - 12x + 5x - 20 = 0
4.) 3x^2 + 7x - 20 = 0

Answer:
= 12
Step-by-step explanation:
The shape ABCDEF is an irregular polygon.
The sum of the interior angles of any regular or irregular polygon = (n - 2) x 180 (where n is the number of sides of the polygon).
Therefore, the sum of the interior angles of shape ABCDEF = (6 - 2) x 180 = 720°
So to find the value of
, we need to add together all the interior angles and equal it to 720, then solve for
.
Before we do that, we need to determine angle F.
From inspection, we can see that angle F and 52° are a linear pair. We know that a linear pair of angles add up to 180°, so F + 52 = 180 ⇒ F = 180 - 52 = 128°
Therefore:
A + B + C + D + E + F = 720
(10
- 5) + 108 + (8
- 3) + (14
- 25) + 133 + 128 = 720
Collect like terms:
10
+ 8
+ 14
- 5 + 108 - 3 - 25 + 133 + 128 = 720
Combine like terms:
32
+ 336 = 720
Subtract 336 from both sides:
32
= 384
Divide both sides by 32:
= 12
