How do you solve 7a-3=3+6a

Answers

Answer 1

Answer:

The calculated value of a in the equtaion is a = 6

How to calculate the value of a in the equtaion

From the question, we have the following parameters that can be used in our computation:

7a-3=3+6a

Rewrite as

7a - 3 = 3 + 6a

Evaluate the like terms

So, we have

7a - 6a = 3 + 3

This gives

a = 6

Divide through the equation by 6

so, we have the following representation

a/6 = 1

Evaluate the quotient on the right hand side

a/6 = 1

Lastly, we have

a = 6

Hence, the value of a in the equtaion is 6.

Which fraction is greater than 1

Answers

any mixed number or improper fraction will be greater than one

In example 2, each fraction has a numerator that is equal to its denominator. Each of these fractions is an improper fraction, equal toone whole (1). An improper fraction can also be greater than onewhole, as shown in example 3.

Will the sum of two linear expressions each with an x-term , always,sometimes,or never have an x-term ? Explain your reasoning

Answers

The sum will have an x-term sumtimes ... whenever
the x-terms alone don't add up to zero.

Examples:

-- Two linear expressions:

   y + x
and
   y + 2x

The sum of the x-terms alone is (x + 2x) = 3x .
So the sum of the expressions has an x-term.

   (y + x) + (y + 2x) = 2y + 3x .
_______________________________

Two different linear expressions:

   y + 3x
and
   y - 3x

The sum of the x-terms alone is (3x - 3x) = zero.
So the sum of the expressions doesn't have an x-term.

   (y + 3x) + (y - 3x) = 2y .

Mario ordered a pizza for dinner when it arrived, mario quickly ate 1/8 of the pizza. while mario went to go get napkins. his pet poodle ate 1/3a.) write a numerical expression to show the fraction of the pizza that is left

Answers

The first thing to do is to make the denominators the same:
1 X 3 = 3. 8 X 3 = 24
1 X 8 = 8. 3 X 8 = 24

3/24 + 8/24 = 11/24

The whole pizza is 1. The one can be written as a fraction:
1/1

1 X 24 = 24

24/24 - 11/24 = 13/24

24/24 - (3/24 + 8/24) = 13/24

1/8+1/3=](3)(1)+(1)(8)]/[(8)(3)]=13/24

What is 12.345 rounded to the nearest tenth

Answers

Rounding to the nearest tenth means rounding to the decimal place directly to the right of the decimal.

The rules of rounding are fairly simple. If the number to the right of the number you are rounding is greater than or equal to 5, you round up. If the number to the right is less than 5, you round down.

Let's take a look at the number 12.345.
First, round to the hundredths place. The number right before the 4 is 5, so we round up. This gives us the number 12.35.
Next, we have to round to the tenths place. The number to the right of the 3 is 5, so we round up as well. This gives us the number 12.4.

Answer: 12.4

The answer to your question 12.3 because it the number the the hundredth place is smaller the 5 you round down

Which statement best explains whether the table represents a linear function or a nonlinear function?

It represents a linear function because it's points are on a straight line

It represents a linear function because it's points are not on a straight line

It represents a nonlinear function because its points are on a straight line

It represents a nonlinear function because it's points are not on as straight line.
