Don't know but
Step-by-step explanation:
The 13th question. The order of operations is Parentheses, Exponents, Multiplication and or division, addition and or subtracting. I can't do the entire thing but 3^{2} =9
Solve:-
Find unit price per pack.
6-Pack:-
2.49 ÷ 6 = <span>0.41
$</span><span>0.41 per can
12-pack:-
3.99 </span>÷ 12 = 0.33
<span>0.33 per can
24-pack:-
5.49 </span>÷ 25 = <span>0.22
</span><span>0.22 per can
</span>
The cheapest is 24-pack, because the unit price for that is the cheapest. After that pack is the 12-pack one because that is cheaper than the 6-pack. and last is the 6-pack. <span />
12x-5+85=128.......12x+80=128......12x+80-80=128-80....12x=48...... divide both sides by 12 to get x=4. Now most people do not complete solving for the missing value....12(4)-5=43 degrees
