9 times 1.23 equals $11.07 so it cost $11.07
10 -3.5 and 10 -8.5 is the answer I think
Area of lane=area of rectangle
=180x5=900m²
Area of brick=0.2x0. 15
=0.03m²
No of bricks needed=900/0.03
=30000
Cost of bricks=30000/1000x750
=30x750=22500
The value of RS in the line segment is 20
To solve for RS :
From the line segment attached :
The information given is :
RS = 3x - 16
ST = 4x - 8
RT = 60
RT = RS + ST
60 = 3x - 16 + 4x - 8
60 = 7x - 24
60 + 24 = 7x
84 = 7x
Divide both sides by 7
84/7 = x
x = 12
RS = 3x - 16
RS = 3(12) - 16
RS = 36 - 16
RS = 20
HENCE, RS = 20
