A+b=15.25
a+f=72.25, since f=13b
a+13b=72.25 so now we have two equation in two variables...
a+13b=72.25 and a+b=15.25 so we can say:
(a+13b=72.25)-13(a+b=15.25)
a+13b-13a-13b=72.25-198.25
-12a=-126
a=10.5 kg
So Abdul's mass is 10.5 kilograms.
The solution set of the inequality −5 < 2x + 3 < 9 is (-4,3)
<h3>How to solve the inequality?</h3>
The compound inequality is given as:
−5 < 2x + 3 < 9
Expand the inequality
−5 < 2x + 3 or 2x + 3 < 9
Rewrite as:
2x + 3 > -5 or 2x + 3 < 9
Subtract 3 from both sides
2x > -8 or 2x < 6
Divide both sides by 2
x > -4 or x < 3
Rewrite as:
(-4,3)
Hence, the solution set of the inequality is (-4,3)
