Ayuda pls

A) 3+a=√25-16

B)10b+15+4=37+46

C)4²+9c+√4=16.5+2+7c

Answer 1

Respuesta:

a) -14. b) b= $\frac{32}{5}$ c) c = 0,25.

Explicación paso a paso:

a) 3+a = $\sqrt{25}$ - 16

3+a = 5 - 16

3+a = -11

a = -11-3

a = -14

b) 10b + 15 + 4 = 37 + 46

10b + 19 = 83

10b = 83 - 19

10b = 64

b = $\frac{64}{10}$

(reducir usando 2)

$B = \frac{32}{5}$

c) $4^{2}$ + 9c + $\sqrt{4}$= 16,5 + 2 + 7c

$4^{2}$ + 9c + 2 = 16,5 + 2 + 7c

$4^{2}$ + 9c = 16,5 + 7c

9c - 7c = 16,5 - 16

2c = 0,5

c = 0,25
