Step-by-step explanation:
Let x be the width of the playground, then 3x is the length of the
<span>playground
х * 3х = 75
3x</span>² = 75
x² = 25
x = 5 m (width)
5*3=15 m (length)
Perimeter = 2(5+15) = 2*20 = 40 meters.
Answer:
Step-by-step explanation:
(a)
Total cost = (7 items * Cost per item) + Shipping fee = 7*6.5 + 8.5 = $54
(b)
Modelling the above equation with symbols:
c = s*6.5 + 8.5 = 6.5s + 8.5
(c)
For a total cost of 80$, c = 80:
80 = 6.5s + 8.5
Calculating, we get:
s = 11 items
Rachel ordered a total of 11 items
12>x
X = the number of golf balls, inequality states that the number of golf balls is over 12
Answer: B.) $1,383.53
Step-by-step explanation:

The speed of crew= 300 bricks/hour
Total hours they take to make the wall= 
The cost of labour =$4,000 per eight-hour
⇒The cost of labour for 1 hour = 
Now, the cost of wall= 
Hence, B is the right answer, the cost of the new wall= $1383.53
