Paulina has read 58 pages of the 234-page book she is doing a book report on for Language Arts. She plans to finish her book by

reading 25 pages each day. Using d for the number of days, write a two-step equation to model this situation that you could solve to find out how many days Paulina took to read the rest of her book. Multiple choice question.
A) 25d – 58 = 234
B) 25d + 58d = 234
C) 25 + 58d = 234

Answer:

D

Step-by-step explanation:

A:

25d - 58 = 234

Add 58 to 58 and 234

25d = 292

Divide 25 from both sides

d = 11

A is incorrect because you need to subtract the pages that have been read.

—

B:

25d + 58d = 234

Combine Like Terms

83d = 234

Divide 83 from both sides

d = 83

B is incorrect because 58 pages aren't days, those are the pages read so this equation is overall incorrect.

—

C:

25 + 58d = 234

Subtract 25 from both sides

58d = 209

Divide both sides by 58

d = 3.603 and so on

C is incorrect because, again, 58 isn't the days its the pages read.

—

D:

25d + 58 = 234

Subtract 58 from 58 and 234

25d = 176

Divide 25 from both sides

d = 7.04

D is the correct answer because 25 is the days and 58 is the pages read. You subtracted 58 from each side, making the number of pages in the book go down because you read those pages. You also divided 176 (the pages left) by the days, so 7.04 is your answer. 7 is the answer rounded down. D is your answer.

Which of the following is the correct graph of the compound inequality 4p + 1 > −7 or 6p + 3 < 33?. . A.a number line with
r-ruslan [8.4K]

We are given compound inequality 4p + 1 > −7 or 6p + 3 < 33.

Let us solve each of the inequality one by one.

4p + 1 > −7

Subtracting 1 from both sides, we get

4p + 1-1 > -7-1

4p > -8

Dividing both sides by 4, we get

p > -2.    <em>  (Shading right side for greater than sign)</em>

Solving 6p + 3 < 33.

Subtracting 3 from both sides, we get

6p + 3-3 < 33-3.

6p < 30

Dividing both sides by 6, we get

p < 5. <em> (Shading left for less than sign)</em>

<em>We have less than and greater than symbols in both inequalities, therefore we would have open circles(dots) on -2 and 5.</em>

And because we have "OR" composite inequality.

<em>So, we would take the combination of both shaded portion.</em>

<h3>Therefore, correct option is C.number line with shading everywhere.. </h3>

Mrrafil [7]

Answer:

  • -32x² +8x -8
  • See below about the process

Step-by-step explanation:

The simplified expression is ...

  3x(x -12x) +3x² -2(x -2)²

  = 3x(-11x) +3x² -2(x² -4x +4) . . . . . simplify contents of parentheses

  = -33x² +3x² -2x² +8x -8 . . . . . . . .eliminate parentheses

  = (-33 +3 -2)x² +8x -8 . . . . . . . . . . group the coefficients of like terms

  = -32x² +8x -8
