Mathematics
1 answer:
butalik [34]2 years ago
5 0

1.  Rewrite one side (or both) by combining like terms. Option C

2. Yes, the equations are equivalent. Option A

<h3>Reasons for the answers</h3>

1.

Equation A ;  2x -1  = 5x

Equation B ; -1 = 3x

To get equation B from equation A

2x - 1 = 5x

Collect like terms

-1 = 5x -2x

Subtract the like terms

-1 = 3x

Thus, rewrite one side (or both) by combining like terms. Option C

2. 2x - 1 = 5x ...... equation A

Solution ;

2x -5x = 1

-3x = 1

x = -1/3

-1 = 3x

Solution;

x = -1/3

Thus, the equations are equivalent. Option A

Vitek1552 [10]

Answer:

Books remaining in  Andrews book collection = 29 books

Explanation:

 Andrews book collection contains 60 books.

 He donates 15% of his books to the national library,

        Number of books to library = 60 x 15/100 = 9

 Sells 1/4 of his books to a book dealer,

        Book sold to book dealer = 60 x 1/4 = 15

 Sells 7 books on amazon.

 Books remaining = 60 - (9 + 15 + 7)

                              = 60 - 31

                              = 29

Books remaining in  Andrews book collection = 29 books

Answer:

10.5

Step-by-step explanation:

ΔXYZ is similar to ΔABC.  So the corresponding sides are proportional:

XY / AB = XZ / AC = YZ / BC

We want to find length AB, so we can either use the first proportion:

7 / k = 3 / 4.5

Or we can use the second proportion:

7 / k = 6 / 9

Either way, we'll get the same answer.  I'll use the second proportion.  Cross multiplying:

6k = 63

Dividing:

k = 10.5
