A(n)=a(1)+d(n-1), d=a(16)-a(15)=-5-(-53)=48
a(15)=a(1)+d*(15-1),
-53=a(1)+48*(15-1),
a(1)=-53-48*14= -725
a(n)=-725+48(n-1)
Answer: 10 bags that weigh 2 lb.

2.5 bags that weigh 8 lb.
Hope this helps.
Step-by-step explanation:
Answer:
Step-by-step explanation:
you know that both angles=180
6x+20+2x+4=180
8x+24=180
8x=180-24
8x=156
x=19.5
angle TQS=19.5*60+20=137
angle SQR=2*19.5+4=43
Answer:
Step-by-step explanation:
Piece of land:
Length = l = 10 m & width = w = 8 m
Area of land = l*w
= 10 * 8
= 80 square meter.
Flower bed:
Side = 2 m
Area of one square flower bed = side * side = 2 *2 = 4 square meter
Area of 5 flower bed = 5 *4 = 20 sq.m
Area of the remaining land = Area of piece of land - area of 5 flower bed
= 80 - 20
= 60 sq. m
2,254
