plz help me and show and follow steps

Step-by-step explanation:

Given: Liam has a bag of b beads. He gives 20 beads to his sister.

Total beads = b+20

Number of necklaces made = 4

If he uses equal amount of beads in each necklace , the number of beads in each necklace = (Total beads) ÷ (Number of necklaces made)

=

Hence, an expression that represents the number of beads on each necklace. =

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
