lara31 [8.8K]

Step-by-step explanation:

We have xy = 28, x² + y² = 65 and x³ + y³ = 407.

Since (x + y)(x² - xy + y²) = x³ + y³,

x + y = (x³ + y³)/(x² + y² - xy)

= (407) / [(65) - (28)]

= 407 / 37

= 11.

Hence the sum of the numbers is 11.

The number of students taking classes at RSM Branch A is 1
juin [17]

Answer:

B = 1320

A= \dfrac54B

Step-by-step explanation:

Let A = number of students at Branch A

Let B = number of students at Branch B

If the number of students taking classes at Branch A is 1/4 more than Branch B, then:

      A=1 \dfrac14B

\implies A= \dfrac54B

If Branch A has 1,650 students, then substitute A = 1650 and solve for B:

\implies 1650= \dfrac54B

\implies 1650 \times 4= 5B

\implies 6600 =5B

\implies B=\dfrac{6600}{5}

\implies B=1320
