9514 1404 393

Answer:

  9 : 49

Step-by-step explanation:

Assuming the rectangles are similar, the ratio of their areas is the square of the ratio of their side lengths.

  sides ratio = 3 : 7

  areas ratio = 3² : 7² = 9 : 49

Answer:

\sf x = \dfrac{n - 2mp}{2m}

Step-by-step explanation:

              \sf 3m = m + \dfrac{n}{p + x}\\

        \sf 3m - m = \dfrac{n}{p +x}

                \sf 2m = \dfrac{n}{p +x}

Now cross multiply,

          2m*(p +x) = n

To open the parenthesis, multiply 2m by p and x.

        2mp + 2mx = n

 Isolate the term with variable 'x'

                    2mx = n - 2mp

Now, isolate 'x', by dividing both sides by 2m

                          \sf  x = \dfrac{n-2mp}{2m}

iris [78.8K]

Answer:

Martina 29, Scott 23 and Jim 69.

Step-by-step explanation:

We are told that:

Martina served six more X orders than Scott (X+6).

So, Scott served X orders.

And Jim served 3 times X order as Scott.

We will have then:

X + (X+6) + 3X = 121

5X + 6 = 121

5X = 121 - 6

5X = 115

X = 115/5

X = 23

So, Scott served 23 orders, Martina 29 and Jim 69.
