Answer:

x = 4 1/2

Step-by-step explanation:

To get to minus 1/2 from plus 2 you would subtract 2 1/2 from 2.

To arrive at x you would add 2 1/2 to 2.

The result is a progression of:  4 1/2, 2, - 1/2

(4 1/2 minus 2 1/2 = 2; 2 minus 2 1/2 = - 1/2)

lutik1710 [3]

Answer:

  V(x) = (x +4)(x +2)(2x +11)

Step-by-step explanation:

For length L = (x+4), the height is ...

  2L +3 = 2(x+4) +3

  = 2x +8 +3

  = 2x +11

The volume is the product of length, width, and height, so is ...

  V = (x +4)(x +2)(2x +11)

what is consecutive whole numbers? I have to write an algebraic expression for the sum of three consecutive whole numbers... :(
Agata [3.3K]

Answer:

Consecutive whole numbers (or integers) are numbers that directly follow one another.

Eg: 1, 2, 3, 4, 5 are consecutive whole numbers.

Step-by-step explanation:

Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108.

or

let the three consecutive whole numbers is x, x+1,and x+2

x + x+1 + x+2 = 4+2(x+1)

3x+3=4+2x+2

3x-2x=6-3

x=3

the other two numbers are 3+1=4,and 3+2=5

so the three numbers are 3,4 and 5

A museum groundskeeper is creating a semicircular statuary garden with a diameter of 29 feet. There will be a fence around the g
Jlenok [28]

Answer:

The fence will cost $330.09

Step-by-step explanation:

First we have to calculate the perimeter of the semicircle for that we use the following formula:

d = diameter = 29ft

s = perimeter of semicircle

π = 3.14

s = d * 1/2 * π

we replace the values that ​​we know

s = 29ft * 1/2 * 3.14

s = 45.53ft

Now we multiply the number of feet by the price of 1 foot of fence

45.53 * $7.25 = 330.0925

Rounding to the nearest hundredth

$330.0925 = $330.09
