Step-by-step explanation:Using unitary method :-
5 kg apple → 600 Rs
1 kg apple →
5
600
= 120 Rs
27 kg apple →120×27=3240 Rs
Solution of a linear inequality
The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.
A,E,F
Sq rt of 25 is 5 and 5 is less than 10
Sq rt of 36 is 6 and 6 is less than 10
Sq rt of 9 is 3 and 3 is less than 10
-7x + 6 =27
subtract 6 from both sides
-7x =21
divide both sides by -7
x= -3
