y de nuevo la ayuda con las 3

Answer 1

43.

a) x / 5 + √(108 - 27) = 3² + 3

x / 5 + √81 = 9 + 3

x / 5 + 9 = 9 + 3

x / 5 = 3

x = 15

b) 3m - 2 + 4 = 21 - 7

3m + 2 = 14

3m = 12

m = 4

c) 2m + 36 = 40 + 2

2m = 42 - 36

m = 3

d) 10 - 7 = 4z -1

4 = 4z

z = 1

44.

x / 3 + 4 = √ 64

x / 3 + 4 = 8

x / 3 = 4

x = 12

45.

x + (x + 1) + (x + 2) = √ 144

3x + 3 = 12

3x = 9

x = 3

∴ Los números son 3, 4 y 5
