sue stacked one box onto another. the bottom had the height of 2 1/3 feet and the top box had the height of 3 2/3 feet. how tall

Scilla [17]

Height of bottom box : - $2 \frac{1}{3} => 7/3$
Height of top box : - $3 \frac{2}{3} => 11/3$

Thus, height of two boxes =

$\frac{7}{3} + \frac{11}{3} = \frac{18}{3} => 6ft$

3 times 2x minus 22 plus 2x equals 8x minus 4

Paladinen [302]

Answer:

x = -9

Step-by-step explanation:

6x-22+2x=8x-4

so first you want to add 4 to both sides so it becomes 6x-18=8x now substract 6x from both sides to get -18=2x now divide that by 2 and you get x= -9
