2*1*1= 2 m^3 per chest
2 m^3 per chest* 18 chests= 36 m^3 total
Final answer: 36 m^3
First you have to know the value of either x or y. If x is 2, and y is 20, it would be false.
But if x is 2 and y is 21, it would be true.
So, the equation is open!
Answer:
-|7-2x|+11= -8
x=-6 0r x=13
9-7|-x-3|= -61
x=-13 or x=7
13|-2x+1|-10=159
x=-6 or x=7
Step-by-step explanation:
-|7-2x|+11= -8
-|7-2x|=-8-11
either :
7-2x=-19
-2x=-19-7
x=-26/2
x=13
Or: 7-2x=19
-2x=19-7
-2x=12
x=-12/2
x= - 6
<h2>9-7|-x-3|= -61</h2>
9−7(|−x−3|)=−61
−7(|−x−3|)=−61-9
−7(|−x−3|)=−70
|-x-3|=-70/-7
|-x-3|=10
either :
-x-3=10 or -x-3=-10
-x=13 -x=-7
x=-13 x=7
<h2>13|-2x+1|-10=159</h2>
13|-2x+1|=159+10
13|-2x+1|=169
|-2x+1|=169/13
|-2x+1|=13
either or
-2x+1=-13 -2x+1=13
-2x=-14 -2x=12
x=-14/-2 x=12/-2
x=7 x=-6
