What is 0.24x − 1.85 3.09 − 2.33x = 1.71

1 answer:

6 0

Was the variable "y" supposed to be part of this equation? If so, perhaps you meant to share the following:

<span> 0.24x − 1.85y = 3.09
− 2.33x = 1.71y

Plese, go back and reread the original question, and then ensure you have shared that question here precisely as it was presented.</span>

The mean distance from the Sun to Earth is 9.29x10^7. Jupiter’s mean distance from the Sun is 4.8388x10^8. What is the differenc

iVinArrow [24]

Answer:

$-3.9098*10^8$

Step-by-step explanation:

1) Convert to Standard Form:

9.29 * 10^7 = 92900000

4.8388 * 10^8= 483880000

2) Subtract 483880000 from 92900000.

$92900000-483880000=-390980000$

3) Convert the difference into scientific notation.

$-390980000= -3.9098 * 10^8$

<em>C would be your best choice.</em>

Ed planned to read 25 pages a day of his favorite book by some deadline. However, he read 8 pages more a day and there were just

GaryK [48]

Answer:

175 pages

Step-by-step explanation:

Let's call 'd' the number of days before the deadline, and 'n' the total number of pages of the book.

We have the following equations:

(1) $25 d = n$ --> if we multiply the number of pages per day (25) times the number of days (d), we get the total number of pages of the book (n)

(2) $(25+8)(d-2)=n-10$ --> he reads 8 pages more per day (so, 25+8), for a number of days equal to (d-2) (d is the deadline), and he reads a total of n-10 pages (because only 10 are left)

We can substitute (1) into (2) and we find:

$33(d-2)=25d-10\\33d-66=25d-10\\33d-25d=66-10\\8d=56\\d=7$

So, the deadline is 7 days, and from eq.(1) we find the number of pages in the book:

$n=25d=25 (7)=175$
