Answer:

2a + 4b = 44

a+b=15

Step-by-step explanation:

Call a the number of chickens, b the number of horses

We have: 2a + 4b = 44

                a + b = 15

               => 2(a+b) = 30

               <=> (2a + 4b) - (2a + 2b) = 14

                     2b = 14

                  => b = 7

                  => a = 8

So 8 chickens, 7 cows.

2. A supermarket display consists of boxes of cereal. The bottom row has 27 boxes. Each row has four fewer boxes than the row be
tresset_1 [31]

Answer:

Step-by-step explanation:

) Nth term = F + (N - 1) x D, where F=First term, N=Number of terms, D=Common difference

6th row = 23 + (6 - 1) x -3

            = 23 + (5) x -3

            = 23 + (-15)

            = 8 - number of boxes in the top row.

 

b) Sum = N/2[2F + (N - 1) x D]

            = 6/2[2*23 + (6 - 1) x -3]

             = 3  [46  +    (5) x -3 ]

             = 3  [46  +      -15 ]

             = 3  [ 31 ]

             = 93 - total number of boxes in the entire display.

Answer:

Fr^2/Gm_2=m_1

Step-by-step explanation:

What you do first is you have to cross-multiply so f*r^2 and 1*gm_1m_2 to get

Fr^2=Gm_1m_2. Next you will divide Gm_2 from both sides to get

Fr^2/Gm_2=m_1 as your answer.
