In a given year, the population of Metro City is 7420, and the population is decreasing by 152 people per year. The population o
Anit [1.1K]

Answer:

The correct option is D.

Step-by-step explanation:

Let <em>x</em> denote the years.

The information provided is:

  • The population of Metro City is 7420.
  • The population is decreasing by 152 people per year.
  • The population of Smallville is consistently 1200 less than half of Metro City.

From the provided data derive the equation for the population of Smallville <em>x</em> years after as follows:

Y = [\frac{1}{2}\cdot (7420-152x)]-1200

The population of Smallville is 2282 after <em>x</em> years.

Compute the value of <em>x</em> as follows:

2282= [\frac{1}{2}\cdot (7420-152x)]-1200

\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3

Thus, the time it will take for Smallville's population to reach 2282 is 3 years.

The correct option is D.

The perimeter of a rectangle is 84 feet. the length is two feet greater than 3 times the width. Find the length and width. Draw
Kipish [7]
The formula for a rectangle's perimeter is

P = 2l + 2w

We know the length is 2 ft greater than thrice the width, so 2l becomes:

3w + 2ft + 3w + 2ft

Substitute.

P = 3w + 2ft + 3w + 2ft + 2w

Add like terms.

P = 8w + 4ft

Substitute P.

84 ft = 8w + 4ft

Subtract 4 ft from both sides to eliminate. (Property of equality)

84 ft - 4ft = 8w + 4ft - 4ft
80 ft = 8w

Divide 8 on both sides to isolate w.

80 ft / 8 = 8w / 8

10 ft = w

We have the value of w, now look for the l which we know is 2 feet more than thrice the value of w.

l = 10 ft × 3 + 2 ft
l = 30 ft + 2 ft
l = 32 ft

Therefore, the length and the width of the rectangle is 10 ft (w) and 32 ft (l).

Check:
84 ft = (2) (10 ft) + (2) (32 ft)
84 ft = 20 ft + 64 ft
84 ft = 84 ft ✔
