Can you please solve and explain how

Answers

If we take 24 h, and think that 150 bolts are produced during 1 hour,

then during 24 hours we will get 150*24 = 3600 bolts.

So, y = 150x represent the number of bolts the machine can produce in x hours.

150 bolts/h, and y =150bolts/h *24 h = 3600 bolts

Answer is B.

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***

Well that's easy. You see first you multiply 3x36 then you multiply 2x24. Now you want to to add this two numbers. Lastly, you subtract 8 from your answer.Hope this helped
First you multiply 3•36 and then multiply 2•24 then add both products and subtract the andwer by 8 (148)
