3x+1+5x=7+15+7x what is x?

baherus [9]

Answer:

Step-by-step explanation:

3x + 1 + 5x = 7 + 15 + 7x combine like terms

(3x + 5x) + 1 = (7 + 15) + 7x

8x + 1 = 22 + 7x subtract 1 from both sides

8x = 21 + 7x subtract 7x from both sides

x = 21

Answer:

$Domain\ =\ \{x: 9,10,11....16\}$

$Range\ =\ \{y:290, 315,340.....465\}$

Step-by-step explanation:

Given

$y = 25x + 65$

Required

Determine the range and domain when x = 9 to 16

The domain is the set of

$Domain\ =\ \{x: 9,10,11....16\}$

Solving for the range;

When x = 9

$y = 25 * 9 + 65$

$y = 225 + 65$

$y = 290$

When x = 10

$y = 25 * 10 + 65$

$y = 250 + 65$

$y = 315$

When x = 11

$y = 25 * 11 + 65$

$y = 275 + 65$

$y = 340$

You continue till you get to x = 16

-

When x = 16

$y = 25 * 16 + 65$

$y = 400 + 65$

$y = 465$

Hence; the range is

$Range\ =\ \{y:290, 315,340.....465\}$

Reemu read 1·5 pages of a book. If she read further 40 pages,she would have read 7.10 pages of the book. How many pages are left

vampirchik [111]

Answer:

Let total pages be x

ATQ,

(x/5)+40=7x/10

(x+200)/5=7x/10

Cross multiply

10x+2000=35x

10x-35x=-2000

-25x=-2000

x=2000/25

x=80 pages

Therefore pages left= 3/10 of pages

=3*80/10=24 pages
