Answer:

x = 2 1/6

Step-by-step explanation:

6 1/4 (x− 2/3 )=9 3/8

Change the mixed numbers to improper fractions

6 1/4 = (4*6+1) / 4 = 25/4

9 3/8 = (8*9 +3) /8 = 75/8

25/4 (x-2/3) = 75/8

Multiply each side by 4/25

4/25*25/4 (x-2/3) = 75/8 *4/25

x-2/3 = 75/25 *4/8

x-2/3 = 3 *1/2

x-2/3 = 3/2

Add 2/3 to each side

x-2/3 +2/3 = 3/2 +2/3

x= 3/2 +2/3

Get a common denominator of 6

x  = 3/2 *3/3    + 2/3 *2/2

x = 9/6 + 4/6

x = 13/6

6 goes into 13 2 times with 1 left over

x = 2 1/6

A right square pyramid has a slant height of 25 feet, and the length of a side
Amanda [17]

Answer:

C. 24 ft.

Step-by-step explanation:

There is a right triangle which can be drawn in side the pyramid with height h, hypotenuse  25 ft and bas = 1/2 * 14 = 7.

So using Pythagoras:

25^2 = h^2 + 7^2

h^2 = 25^2 - 7^2

h^2 = 576

h = √576 = 24 ft.
