Given that 2 x − 2 y = 23 Find x when y = 9
Answer:
[tex]x=41/2=20.5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]2x-2y=23[/tex]
And we want to find x when y is 9.
So, substitute y for 9 and solve for x:
[tex]2x-2(9)=23[/tex]
Multiply:
[tex]2x-18=23[/tex]
Add 18 to both sides:
[tex]2x=41[/tex]
Divide both sides by 2:
[tex]x=41/2=20.5[/tex]
So, our answer is 20.5
Answer:
20.5
Step-by-step explanation:
2x - 2y = 23
2x - 2(9) = 23
2x - 18 = 23
2x = 23 + 18
2x = 41
x = 20.5

use deductive reasoning to write a formula for the perimeter P of a regular polygon with n sides, where each side is s.
Step-by-step explanation:
If each side is s and the regular polygon has n sides, then the perimeter P must be n * s.
Equation for perimeter of regular polygon = ns
Given that;
Number of sides of regular polygon = n
Length of each side = s unit
Find:
Equation for perimeter of regular polygon
Computation:
Perimeter of regular polygon = [Number of sides of regular polygon[[Length of each side]
Equation for perimeter of regular polygon = [n][s]
So,
P = ns

Tom made a square measuring 8 feet by 8 feet, and had 18 friends stand inside it as if they are watching a band at a small club. Find the ratio of this number to the rectangle’s area. Choose the appropriate label for this ratio.
Answer:
The ratio of this number to the rectangle’s area is 9:32.
Step-by-step explanation:
The information provided are:
Tom made a square measuring 8 feet by 8 feet.He had 18 friends stand inside it as if they are watching a band at a small club.The area of the square is:
A = (side)²
[tex]=(8\ \text{feet})^{2}\\\\=64\ \text{feet}^{2}[/tex]
The number of people standing insider the square is:
n = 18
Compute the ration of n to A as follows:
[tex]n:A=18:64[/tex]
[tex]=\frac{18}{64}\\\\=\frac{9}{32}\\\\=9:32[/tex]
Thus, the ratio of this number to the rectangle’s area is 9:32.

The width of a rectangle measures (4.4d-4.3)(4.4d−4.3) centimeters, and its length measures (7.6d+4.7)(7.6d+4.7) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
Perimeter, P = (24d+0.8) cm
Step-by-step explanation:
Given that,
Width of rectangle, B = (4.4d−4.3) cm
Length, l = (7.6d+4.7)
Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,
Perimeter = 2(L+B)
P = 2[(7.6d+4.7)+(4.4d−4.3)]
Collecting like terms
P = 2[(7.6d+4.4d)+(4.7−4.3)]
P=2(12d+0.4)
⇒ P = 24d+0.8
So, the expression for the perimeter of the rectangle is (24d+0.8) cm.
