900 students attended the school concert. There were twice as many adults as children in the audience. How many children attended the concert? which let statement would you use?

Answers

Answer 1
Answer: I am slightly confused by your wording in the last sentence, but if you are trying to figure out how many children attended the concert you would use the second statement. The first statement does not tell you if the students are "children" are not so that is not an appropriate choice.

The number that rode in columns was 3 2/3 times the number that rode in rows. If 2200 rode in columns, how many rode in rows?

Answers

Answer:

600

Step-by-step explanation:

Given parameters:

    Number that rode in columns = 3(2)/(3) times the number that rode in rows.

       2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

  Let the number of people that rode in columns  = C

   Let the number of people that rode in rows  = R

                 C = (11)/(3)R

Number of people that rode in rows  = 2200;

            2200 =  (11)/(3)R

             11R  = 2200 x 3

                R  = (2200 x 3)/(11)

                R = 200 x 3

               R  = 600

Number of people that rode in rows  = 600

Answers

Answer:

The expression given in the question i.e 6x + 6 + 5x - 8 in the simplified form is 11x -2 .

Step-by-step explanation:

As given the expression in the question be as follow .

= 6x + 6 +5x -8

Simplify the above expression and it can be written as .

= 6x + 5x + 6 - 8

= 11x -2

Therefore the expression given in the question i.e 6x + 6 + 5x - 8 in the simplified form is 11x -2 .

11x-2; SInce you have to add 6x and 5x because they are 'like terms' meaning they share the same variable. You also add the 6 and the -8, which is basically doing 6-8, which equals -2. So, you put these two numbers together to get an expression of 11x-2.

What two numbers add up to -15 & can be multiplied to get 56

Answers

-8 and -7, I used guess and check
-8 and -7,because when you add those two numbers,you get -15 because their both negative numbers,and iff you multiply them,they equal 56 because negative times a negative equals a positive.ur welcome!:)
