720/18 = 40

Find length:

40*13 = 520

520/2 = 260 <-- must divide by 2, 520 is the sum of twice the length

Find width:

40*5 = 200

200/2 = 100 <-- must divide by 2, 200 is the sum of twice the width

can someone help me with this, i have a hard time doing math it would really be nice if you could help me

Answers

Answer:

see explanation

Step-by-step explanation:

let the two consecutive odd numbers be n and n + 2 , then

n + n + 2 = 148 , collect like terms

2n + 2 = 148 ( subtract 2 from both sides )

2n = 146 ( divide both sides by 2 )

n = 73

n + 2 = 73 + 2 = 75

The 2 numbers are 73 and 75

----------------------------------------------------------------

let width be w then length = 2w - 6

The perimeter (P) is calculated as

P = 2(width + length) , then

2(w + 2w - 6) = 54 ( divide both sides by 2 )

w + 2w - 6 = 27 , collect like terms

3w - 6 = 27 ( add 6 to both sides )

3w = 33 ( divide both sides by 3 )

w = 11

2w - 6 = 2(11) - 6 = 22 - 6 = 16

length = 16 in and width = 11 in

Hello,

Answer: 73,75

Step-by-step explanation:

1st Question Answer

x -> 1st

x+2 -> 2nd

So... Since it is equal to 148 then we write...

x+x+2=148

Combine Like Terms

2x+2=148

Subtract 2 from both sides

2x=146

Divide 2 to both sides

x=73 and +2 = 75

In Final: The two consecutive odd integers are 73 and 75

2nd question)

Width of rectangle is x inches

2x-6

Since perimeter = 2(length+witdth)

54 = 2(2W - 6) + 2W,  (substitute P = 54 and L = 2W - 6)

66=6w

w=11

To find the length: Substitute

54=2l+2(11)

32=2L

L=16

Step-by-step explanation:

To get from 22 to 22000, you need to times by 1000. The power in this case represents the amount of zeros added to a number. Hope this helped!

10³ multiply 22 by to get an answer of 22,000.

The correct option is (D)

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

We have to multiply 22 such that it gives 22, 000.

let the number that being multiplied be x.

So, 22x = 22000

x= 22000/22

x= 1000

x= 10³

Hence, 10³ multiply 22 by to get an answer of 22,000.

1. Which of the following is the slope-intercept form of 6x + 2y = 28?

y=-3:2 – 14
y=-3x + 14
y= 3.c + 14
y= 3x - 14

Answers

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

6x + 2y = 28 ( subtract 6x from both sides )

2y = - 6x + 28 ( divide the terms by 2 )

y = - 3x + 14 ← in slope- intercept form

Answer:

y= -3x + 14

Explanation:

6x + 2y=28

2y= -6x +28

Therefore, y= -3x +14
