Answer:
3re one down
Step-by-step explanation:
0 is rational
First I subtracted the tip: 53.70-9.60=44.10 and then I divided that by 2 because each one of them payed equal amount:44.10/2=22.05. They each payed $22.05
Answer:
Step-by-step explanation:
2 | x + 5.3 | = 4.2
| x + 5.3 | = 4.2 / 2
| x + 5.3 | = 2.1
x + 5.3 = 2.1 x + 5.3 = - 2.1
x = 2.1 - 5.3 x = -2.1 - 5.3
x = - 3.2 x = - 7.4
solution is : x = -3.2 or x = -7.4
The given inequality :

Simplify :
<em>Multiply both side by (-1) and reverse the inequality :</em>
<em />

<em>Divide the inequality by 3:</em>
<em />

<em>i.e. x is less than or equal to (-3) </em>
Solution : x ≤ (-3)
<em>so, </em>
<em>x is lies in the half open interval of - infinity to (-3)</em>
<em />
Interval Notation : (-infinity, -3]
