Answer:

below

Step-by-step explanation:

longest side = x+ x/2 + 11-×= 54

×/2 = 54-11

×=21.5 (longest side)

longest side = 21.5 ft

second side = 21.5 / 2 = 10.75 ft

third side = 21.5 - 11 = 10.5 ft

Richard and Teo have a combined age of 37. Richard is 4 years older than twice Teo's age. How old are Richard and Teo?

valkas [14]

Answer:

Teo is 11 years old and Richard is 26 years old.

Step-by-step explanation:

Let R be the age of Richard and T be the age of Teo.

First set up the equations:

The combined age of Teo and Richard is 37:

R+T=37

Richard is four years old than twice Teo's age:

R=2T+4

Then, solve the equations:

Substitute (2) to (1) and solve for T:

(2T+4)+T=37

3T=11

T=11

Solve for R using (2):

R=2(11)+4

R=22+4

R=26
