Answer:
x=3
y=5
Step-by-step explanation:
3×3=9
5×5=25
9+25=34
[3^2+5^2=34]
3^2=9
2×5=10
9+10=19
[3^2+2×5=19]
Answer:

x=27.5
Answer:

Step-by-step explanation:
Given

He can lift less than 135 implies that, his maximum is:

Required
Determine the additional weight
Let the additional weight be x
Such that


Substitute x + 46 for Total in 

<em>Hence, the inequality that describes the scenario is: </em>
<em></em>
Let
be the number of minutes.
The first tank starts with 1500 liters, and loses 4 liters per minute, so after
minutes there will be
liters of water.
The second tank is filled at 6 liters per second, i.e.
liters per minute.
So, there will be
liters of water in the second tank after
minutes.
The two quantities will be equal when
so, approximately, after 3.3 minutes.
