A midpoint divides a line segment into two congruent segments. So, if point U is the midpoint of RS, then that means that RU and SU are congruent.

If RU is 12, then SU is also 12.

So, the whole length of SR is 24.

1) Solution: 24

The midpoint and segment congruency statement in the first problem also applies to the second problem.

SV = TV

2x = 11

Divide both sides by 2 to get x by itself.

x = 5.5

2) Solution: 5.5

Naya [18.7K]

Answer:

8 ejercicios

Step-by-step explanation:

De acuerdo a la información dada, puedes plantear las siguientes ecuaciones:

x+y= 45 (1)

7x-1y= 19 (2)

x= ejercicios que resolvió bien

y= ejercicios que resolvió mal

Primero, puedes despejar x en (1):

x= 45-y (3)

Segundo, debes reemplazar (3) en (2):

7(45-y)-1y=19

315-7y-1y= 19

315-8y= 19

315-19= 8y

296= 8y

y= 296/8

y= 37

Tercero, debes reemplazar el valor de y en (3) para encontrar x:

x= 45-37

x= 8

De acuerdo a esto, la respuesta es que el hijo ha resuelto bien 8 ejercicios.
