Step-by-step explanation:
6x+9= -15
-9. -9
6x= -24
X= -4
Let b = x
a = x + 773
x + <span>x + 773 = 177973
2x + </span><span>773 = 177973
2x = </span>177973<span> - 773
2x = 177200
x = </span>177200<span>/2
x = 88600
The other is x + 773, = 8860</span>0<span> + 773 = 89373
Each country is </span><span>88600</span> and 89373 square kilometers.

Answer:
The number of weekday hours are 5.
Step-by-step explanation:
<em>Let the number of weekday hours be "x".</em>
<em>The total week hours are 26, then number of weekend hours is (26-x) .</em>
<em>The charges for weekdays are $2 per hour and for weekends $10 per hour.</em>
The total money spent is $220.


x = 5.
Thus weekday hours utilized are 5 hours, and weekend are (26-5) 21 hours.
