X=5+y
x+y=-15
subsitute 5+y for x
5+y+y=-15
5+2y=-15
minus 5 from both sides
2y=-20
divide both sides by 2
y=-10
sub back
x=5+y
x=5-10
x=-5
the numbers are -10 and -5
Your answer would be -1/6
The water will last for 3 days
<em><u>Solution:</u></em>
Given that, village having a population of 4000, requires 150 litres of water per head per day
<em><u>Let us first find the volume of tank</u></em>
The tank measuring 20m x 15m x 6m
Length = 20 m
Breadth = 15 m
Height = 6 m


Thus volume of tank is 1800 cubic meter
From given,
Water required per person per day = 150 liters
<em><u>Therefore, water required for 4000 people per day is:</u></em>

Convert to meters

<em><u>How many days will the water of this tank last?</u></em>


Thus the water will last for 3 days
Answer: (A) If it is a bib, then it is a bab
<u>Step-by-step explanation:</u>
p: The bib is a bub.
Rewrite it as: If it is a bib, then it is a bub.
- hypothesis: It is a bib
- conclusion: It is a bub
q: The bub is a bab.
Rewrite it as: If it is a bub, then it is a bab
- hypothesis: It is a bub
- conclusion: It is a bab
The conclusion of p equals the hypothesis of q so the Law of Syllogism can be applied --> hypothesis of p → conclusion of q
The answer is -3.
If we add positive one/+1 to negative four/-4, we subtract +1 from -4, giving us -3.
