Question

Necesito ayuda con esas ecuaciones

Answer 1

d)3.3x=13.2

33x10=13.2

33x10=66/5

33x=132

x=4

e)0.25x=1.75

x/4=1.75

x/4=7/4

x=7

f)2x=8.25

2x=33/4

x=33/8

x=4

Answer 2

Aquí te dejo mi respuesta:

d) 3.3x = 13.2

    x = 13.2/3.3

    x = 132/33

    x = 4

e) 0.25x = 1.75

   x = 1.75/0.25

   x = 175/25

   x = 7

f) 2x = 8.25

   x = 8.25/2

   x = 825/200

   x = 33/8 = 4 1/8 = 4.125

g) 3/4 x = 1/2

   x = 1/2 × (4/3)

   x = 1×4/2×3

   x = 4/6

   x = 2/3 = 0.666666667

h) 5x/6 = 4/5

    5x = 4/5 × 6

    5x = 4×6/5

    5x = 24/5

    x = 24/5×5

    x = 24/25 = 0.96

i) 2x/5 = 2/3

  2x = 2/3 × 5

  2x = 2×5/3

  2x = 10/3

  x = 10/3×2

  x = 10/6

  x = 5/3 = 1 2/3 = 1.666666667

Espero haberte ayudado :D
