The sum of two numbers is 24. Their difference is 15. What are the two numbers?

Answers

x+y = 24x-y = 15 Thus, x=15+y Substitute for x in first equation becomes 15 +y + y = 24. 2y=9; therefore y=4.5, and since x = 24-y, x= 19.5 Check answer: 4.5 + 19.5 = 24; 19.5-4.5 = 15

What is the solution of the linear equation -12+3b - 1 = -5 - b

Answers

Answer:

The solution of the given linear equation is 2.

Step-by-step explanation:

$-12+3b - 1 = -5 - b$

Step 1 :Take all the like terms on same side

$-12+5 - 1 = - b- 3b$

Step 2 :

$-8=-4b$

Step 3 :

$b=(-8)/(-4)=2$

The solution of the given linear equation is 2.

$- 12 + 3b - 1 = - 5 - b \n \n - 13 + 3b = - 5 - b \n \n - 8 = - 4b \n \n b = 2$

First, add both sides by 5 and then subtract both sides by 3b

An art gallery has 18 paintings and 4 photographs displayed in equal rows on a wall,with the same number of each type of art in each row.which of the following could be the number of rows?A 2 rows, B 3 rows, C 4 rows, D 6 rows

Answers

The question is asking us to determine the number of rows in which 18 paintings and 4 photographs could be displayed, such that there should be the same number of each type of art in each row. First we have to find the GCF ( the Greatest Common Factor ) of 18 and 4. 18 = 2 * 3 * 3 and 4 = 2 * 2. The prime factors of 18 are 2 and 3 and the prime factor of 4 is 2. Therefore GCF ( 18, 4 ) = 2. There could be 2 rows, with 9 paintings and 2 photographs in each. Answer: A . 2 rows.
