Answer:

the answer is 12

Step-by-step explanation:

since the triangle is equilateral meaning all side of ABC is equal to each other AB= BC = AC= 8cm and MN is the middle line that divides AB and BC by two

thus, MB =BN= 4 cm. MN is the middle line thus will also be equal to the half of AC  meaning MN=AC/2= 4cm. and perimeter  is MBN = MN+MB+BN= 4cm+4cm+4cm =12cm

astraxan [27]

Answer:

$74.3 <em>is the total amount.</em>

<em> </em>

The first step in this problem is to figure out how much of a tip was left. To find that out, you need to multiply the percentage by the total of the meal.

63 * .18 = 11.34

We know that 11.34 was how much of a tip that was left,

To figure out the total amount that was spent, you would add the total amount and the tip.

63 + 11.34 = 74.34
