6n = 30 + 3(n – 4) for n.

Answers

Answer 1
Answer:

Answer:

n=6

Step-by-step explanation:

6n = 30 + 3(n – 4)

Distribute

6n =30 +3n -12

Combine like terms

6n = 18 +3n

Subtract 3n from each side

6n-3n = 18+3n-3n

3n = 18

Divide each side by 3

3n/3 =18/3

n =6

A father requires his son to do chores for 4 to 6 hours a week. If the son wants to dochores daily, how many hours per day is this (in interval notation)?

Answers

Answer:

I believe the answer is the first one [4/7 ,6/7].

I used process of elimination

The fourth one is unreasonable and impossible.

The third one is more than the weekly requirement.  

The second one is the weekly requirement.

The first one would have to be in reason because of that.

Grace has $100. She is buying charms for her bracelet that cost $5 each. Write an equation showing the relationship between the number of charms,c, she buys and the amount of money she has left,m.

Answers

The required equation is m = 100-5c.

What is an equation?

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, Grace has $100. She is buying charms for her bracelet that cost $5 each.

Let, she buys c charms for her bracelets,

Therefore, the equations become,

m = 100-5c

Where, m is money is she left with.

Hence, the required equation is m = 100-5c.

I’m really confused

7x - 4 = -2x + 1 + 9x - 5

Answers

7X - 9X + 2X = 1 - 5 + 4

7X - 11X = 1 - 9

- 4X = -8

X = -8 (divided) -4

X = 2
I’m also confused. Idk what you want. But im guessing its solving for x. If so, I will walk you through it.

7x-4=-2x+1+9x-5 first simplify it
7x-4=7x-4

Now you get something to where x has infinite solutions.

Seriously. Try to fill in x with any number and the problem will be correct.

The reason it works is because theres no possible way you can find what x is and the rest of the problem is still equal.

We want to try to get x all on one side but that’s impossible with this equation. So we just say x has infinite solutions.

***the answer is x has infinite solutions***
