Answer:

A= 10, B= 22

Step-by-step explanation:

A +B= 32 -----(1)

A: B= 5: 11

Rewriting the above ratio as a fraction:

[tex] \frac{A}{B} = \frac{5}{11} [/tex]

Multiply both sides by B:

[tex]A = \frac{5}{11}B[/tex] -----(2)

Substitute (2) into (1):

[tex] \frac{5}{11}B + B = 32[/tex]

[tex] \frac{16}{11} B = 32[/tex]

[tex]B = 32 \div \frac{16}{11} [/tex]

[tex]B = 32 \times \frac{11}{16} [/tex]

B= 22

Substitute B= 22 into (1):

A +22= 32

A= 32 -22

A= 10
