A gardener has a rectangular flowerbed. The length of the flowerbed is 5 feet more than the width. The perimeter of the flowerbed is 70 feet. Which equation can be used to find the width w in feet?
A. 2w + 5 = 70
B. 2(w+ 5) = 70
C. 2(2w+5) = 70
D. w(w+5) = 70
Answers
So widths plus the 5 feet, then multiple by 2 (the two widths of the rectangle) equal the number of the perimeter of the flowerbed (70 feet).
2(w+5)=70
The equation for the perimeter is 2(2w + 5) = 70, to calculate the width.
What is a rectangle?The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.
Given the perimeter of a rectangular flower bed = 70 feet
and the length of the flowerbed is 5 feet more than the width,
let width be w
length = w + 5
perimeter is given by = P = 2(l + b)
P = 2(w + w + 5)
P = 2(2w + 5)
Hence option C is correct to find the width of the rectangular flowerbed.

Solve for b
Solve for b : -3b+2.5=4
Answers
Answer: -0.5
Step-by-step explanation:
-3b = 4-2.5
-3b = 1.5
(-3b)/-3 = 1.5/-3
b = -0.5
Answer:
should be - 0.5
Step-by-step explanation:
- 3b + 2.5 = 4
1.Turn the equation around
1. -3b = -2.5 + 4.
1. The reason why you turn the 2.5 into a negative is because you basically doing the oppisite if that makes sence.
2. Add -2.5 + 4
2. -2.5 + 4 = 1.5
2. I just added.
3. Plug 1.5 into the equation. Like so
3. -3b = 1.5
3. I just replaced -2.4 + 4 with the answer
4. Divied -3b = 1.5
4. -3b/-3b = 1.5/-3b = -0.5
4. What you do to one side you have to do to the other so -3b/-3b is 0 or it just is not there anymore next you take -3b and divide it by 1.5 and get - 0.5 BAM.
5. Plug -0.5 in for b.
5. -3(-0.5) + 2.5 = 4

A helicopter landing pad has a length of 80 ft and a width of 50 ft. A safety zone of uniform width, which is not to be entered during landing, surrounds the landing pad. The landing pad and safety zone together have a combined area of 10800 ft2, what is the uniform width (safety zone) around the landing pad?
Answers
Step-by-step explanation:
Let w be the uniform width of the safety zone.
We have combined area = 10,800ft².
=> Combined area = Length * Width
= (80 + 2w)(50 + 2w)ft².
Therefore (80 + 2w)(50 + 2w) = 10,800.
=> 4,000 + 260w + 4w² = 10,800
=> 4w² + 260w - 6,800 = 0
=> w² + 65w - 1,700 = 0
=> (w - 20)(w + 85) = 0
=> w = 20 or w = -85
(w = -85 is rejected as width must be positive)
Hence the uniform width is 20ft.

Given the following data:
Numbers = 24 and 45.What is geometric mean?Geometric mean is an average value that is used to indicate the central tendency of a data set containing a group of numbers, especially by determining the product of their values.
Mathematically, geometric mean is given by this formula:
[tex]G=\sqrt[n]{x_1x_2...x_n}[/tex]
Substituting the given parameters into the formula, we have;

compare using >,=,or <. -1.5_____-3/2. -4/5_____-5/4. -3/5_____-6/10. -2/3_____1/3
Answers
Answer:
-1.5 = -3/2
-4/5 > -5/4
-3/5 = -6/10
-2/3 < 1/3
Step-by-step explanation:
If you convert -3/2 into a decimal, it equals -1.5
-5/4 is an improper fraction which makes it greater than one, but since it is negative, it is further away from zero making it less than -4/5
-3/5 is the simplified form of -6/10. 3x2= 6 and 5x2=10
1/3 is positive making it greater than any negative
