Solve and show your work.<br><br> 12-[2 + 6 ÷ (10 - 2³)]

Svet_ta [14]

Answer:

7

Step-by-step explanation:

$2^{3} = 8$
Plug 8 in: 12 - [2 + 6 ÷ (10 - 8)]
10 - 8 = 2
Plug 2 in: 12 - [2 + 6 ÷ (2)]
6 ÷ 2 = 3
Plug 3 in: 12 - [2 + 3]
2 + 3 = 5
Plug 5 in: 12 - 5
12 - 5 = 7

Hiii guys i need help with my homewrok <img src="https://tex.z-dn.net/?f=-9%5Cleq%207-8x" id="TexFormula1" title="-9\leq 7-8x" a

Illusion [34]

Answer:

The answer is x ≤ 2.

Step-by-step explanation:

Firstly, you have to move the unrelated term to the other side :

$- 9 \leqslant 7 - 8x$

$- 9 - 7 \leqslant - 8x$

$- 16 \leqslant - 8x$

Next you can solve it :

$- 8x \geqslant - 16$

$x \leqslant - 16 \div - 8$

$x \leqslant 2$

*Remember to change the symbol, when it is dividing by a negative value
