alguien me ayuda con esto ​

Answer 1

Respuesta:

1. x =6

2. x =10

3. x= 9

4. x= 8.06

5. x= 4.5

Explicación paso a paso:

1.

x = 10*9 /15

x = 90/15

x = 6

2.

x = 14*15 /21

x = 210/21

x = 10

3.

x = 6*6/4

x = 36/4

x = 9

4.

x*x = 2.5*26

x² = 65

x = √65

x= 8.06

5.

x = 3.5*9 /7

x = 31.5/7

x = 4.5
