Assume the number to be ‘x’.

54 + 4x = 21

4x = 21 - 54

4x = -33

x = -33/4

x = -8.25

Answer:

- 8.25

Explanation:

let the unknown number be represented by x.

54 + 4x = 21

(subtract 54 from both sides)

4x = - 33

(divide both sides by 4)

x = <u>- 8.25</u>

i hope this helps! :D

1)96/8=12
2)(95*6+5)/6 : (24+1)/3 = (95*6+5)/6 : 2*25/6 = 575/6 *6/50=575/50
=23/2=11 1/2
11 1/2

3) (11 1/2)*12 area of the one  type of the wall, there are 2 such walls
 (11 1/2)*12*2
(8 1/3)*12 area of the second type of the wall, there are 2 such walls
(8 1/3)*12 *2

Altogether area of the walls:
(11 1/2)*12*2 + (8 1/3)*12 *2=12*2(11 1/2 + 8 1/3)= =24(19+3/6+2/6)=24(19+5/6) = 456 +24*(5/6)= 456+20= 476
