The sum of three consecutive odd numbers is 81. what is the smallest of the three number?

Answers

Answer 1
Answer: 81=x+x+1+x+2 given
81=3x+3 combine like terms
-3-3 subtraction property of equality
78=3x
/3/3 division property of equality
26=x symmetry property 
x=26
x+1=27
x+1=28/
26,27,28
26+27+28=81
so,26.27.and 8

When solving an equation why do you apply the inverse on
 the given operation to both sides

Answers


You can do anything you want to one side of an equation.
You'll usually apply an inverse operation to make the side
simpler, for example to get rid of the 'x', or to get rid of the
fractions on that side.

But when you do something to one side of the equation,
you MUST do exactly the same thing to the other side too.
If you don't, then you have changed the equation to a
different one, and the solution to the one you have now
is not the solution to the original one.

Very simple example:

Solve the equation            2x = 2

Correct solution:
Divide each side by  2 :      x = 1

Incorrect solution:
Divide the left side by  2 :    x = 2

Kristen is making lanyards for a convention. She needs to make 1,000 lanyards and knows that 1 lanyard uses 1.75 feet of cord. How much cord will Kirsten need? Describe how Kirsten could have solved the problem without writing out the pattern needed.

Answers

1,750 feet of cord
She needs 1000 lanyards and therefore 1000 times the amount of cord for 1 lanyard, so if 1 lanyard uses 1.75 feet of cord, 1000 lanyards needs 1000 times 1.75 feet of cord.
1000*1.75ft=1,750ft
She needs 1,750 feet of cord.
1 lanyards = 1.75 ft of cord
1000 lanyards = 1.75 x 1000
1.75 x 1000 = 1750 hope i helped

How do you simplify this expression ? 9•(7-4)^2+9

can you PLEASE show in words and explain your answer i need help!

Answers

Answer:

90

Step-by-step explanation:

we have:

9*(7-4)^2+9

we subtract 7 and 4: 7-4

we have:

9*(3)^2+9

we know: 3^2=3*3=9

so we have:

9*9 +9

we multiply 9 by 9: 9*9 = 81, so we have:

81+9

90

Answer:

\Huge \boxed{90}

Step-by-step explanation:

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract numbers from left to right. Please Excuse My Dear Aunt Sally!

First, parenthesis.

(7-4)=3

9*3²+9

Next, exponent.

3²=3*3=9

9*9+9

Then, multiply numbers from left to right.

9*9=81

Add numbers from left to right.

81+9=90

Therefore, the correct answer is 90.

pls help...1.The given right rectangular prism is composed of small cubes. Find the following is the volume of the prism and the volume of one of the small cubes.

Answers

The volume ofthe rectangular prism is: 1.39 ft³

The volume ofone of the small cubes is: 0.0046 ft³

What is the Volume of a Rectangular Prism?

Volume of rectangular prism = length × width × height

Given the following:

Length = 1 ft

Width = 5/6 ft

Height = 1⅔ ft

Volume of the rectangular prism = 1 × 5/6 × 1⅔ = 1 × 5/6 × 5/3

Volume of the rectangular prism = 25/18 = 1 7/18 ft = 1.39 ft³

Length of the edge of 1 cube = 1/6 ft

Volume of the 1 cube = (1/6)³ = 1/216 = 0.0046 ft³

brainly.com/question/12917973

Answer:

1. 1.3778  2. 0.0089

Step-by-step explanation:

to find the volume of the whole rectangle prism you would have to do the volume formula since it is a 3d shape. VOLUME FORMULA, LxWxH.

so 1x0.83x1.66= 1.3778

you can always convert the fraction into decimal to help you calculate the problem.

i don't know if this is correct but i give it a try, so if the whole volume of the triangle is 1.3378 than you can divide that by the the number of small cubes it has inside.

it is 5 by 10 so there are 150 cubes in total.

1.3378 divided by 150=0.0089

im confident about the 1st but not so much with the second
