[Easy Question] Answer this with evidence of the answer that you provided with me!
monitta

Answer:

48

To start you will find the area as if it was a rectangle. To do that you have to do 8x12. 8x12 = 96, but to find the area of a triangle you take the area of the rectangle and divide it by 2. 96 divided by 2 is equal to 48.

There are other methods of solving this but I think this is the easiest way!

The sum of three numbers is 27 the second number is three times the first while the third is twice the first find their average
Leviafan [203]

Answer:

9

Step-by-step explanation:

x = first number

3x = second number

2x = third number

27 = x + 3x+ 2x

27 = 6x

x=4.5 (first number)

3(4.5) = 13.5 (second number)

2(4.5) = 9 (third number)

(4.5 + 13.5 + 9) /3 = 9

Wow after doing all that I realized that all you had to do was 27/3 since there's 3 numbers.

When cai traveled from new orleans to the ozark mountains in arkansas the elevation changed from 7ft below sea level to 2,314 ft
Tanya [424]

Answer:

2321 ft.

Step-by-step explanation:

When Cai traveled from New Orleans to the Ozark Mountains in Arkansas the elevation changes from 7 ft below sea level to 2314 ft above sea level.

If we consider the elevation below sea level as negative and the elevation above sea level as positive, then the elevation changes from - 7ft to +2314 ft.

Therefore, the increment of elevation is by [2314 - (- 7)] = 2321 ft. (Answer)
