Answer:

Step-by-step explanation:

6.1) let the number be x , so equation will be x+13=27

6.2) Let the number of boys be x and number of GIRLS be y

So from given condition , y=x+50

and , x+y=1070 ,

Substituting y=x+50 we get

= x+x+50 = 1070

= 2x =1020

x=510

Putting x = 510 in y=x+50

y=510+50 = 560

Hence number of girls is 560

6.3) Sum of COMPLEMENTARY angle = 90

let the angles be x and y

From given CONDITIONS , x-y = 20 and x+y =90

On solving the equations we get ,

x = 55 , and y =35
