Answer 1

Answer:

Welcome to Brainly

n-8+3n<-4

Simplify both sides of the inequality

4n-8<-4

Now add 8 to both sides so we can eliminate the -8

4n-8+8<-4+8

4n<4

Divide both sides by 4 so we can find the value for n

4n/4<4/4

n<1

Now how to graph this solution

1) Draw a straight line

so we have x in the positive side and -x the negative side

Our answer is n<1

You will start your line from right to left

so you will start from point 1 to -8

You got it ? if not please let me.

0.25k + 1.5 − k − 3.5
Combining like terms with rational coefficients

Answers

Answer:

- 0. 75 k - 2 .

Step-by-step explanation:

Given : 0.25k + 1.5 − k − 3.5

To find : Combining like terms with rational coefficients.

Solution : We have given 0.25k + 1.5 − k − 3.5.

On combining like term

0.25 k - k + 1.5 - 3.5.

- 0. 75 k - 2 .

Therefore, - 0. 75 k - 2 .

−0.75k−2 is the answer to this equation
