solve 2x+6=34 i have no idea pls exsplain and help me :)

Answers

You want to try to isolate the x:
First subtract 6 from both sides so you get 2x=28

Then divide both side by 2 so you get x=14 which is your answer :)

ANSWER: x=14

Answer:

14

Step-by-step explanation:

okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this

so you’re gonna start off by separating the 2x from the 6=34.

now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)

now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.

2 x 14 + 6 = 34?

2 x 14 = 28 + 6 = 34.

34 = 34

so, x is 14. hope this helped!

The test will cover 120 pages in his textbook. He has read only 36 pages. If he plans to read an equal amount every day of the week to finish the 120 pages, how much must read each day?

Answers

Answer:

He must read each day=12 pages

Step-by-step explanation:

We are given that

Total number of pages in textbook=120

He has read number of pages=36

Number of days in a week=7

We have to find the number of pages read each day to finish 120 pages in a week.

Number of pages remaining for reading=120-36

Number of pages remaining for reading=84

Now,

Number of pages read each day=[tex]\frac{84}{7}[/tex]

Number of pages read each day=12

Hence, he must read each day=12 pages

Enter your answer with one decimal place.

Answers

(10m-30) = 28. 28 plus 30 is 58 and 58/10 is 5.8. M is 5.8.
28 = 10m - 30

28 + 30 = 10m

58 = 10m

10m = 58

m = 58/10

m = 5.8
