Question

halla el valor de x en cada proporción

Answer 1

Explicación paso a paso:

–2/12 = –X/48

–1/6 = –X/48. /×-1

1/6=X/48

48=6X

48/6=X

X=8

–9/⅛=36/X

–9X = ⅛×36

–9X = 36/8=13/4

–9X=13/4

X=13/4 / –9/1

X = 13/ –36

X= –1/2

X/3 = 5/225

225X = 15

x = 15/225

X = 1/15

6/X+1 = 5/40

240 = 5X+5

235/5 = X

X= 47

9/4 / X = 9/24

9/4 × 24 = X × 9/24

216 / 4 = 9X / 24

54 = 3X / 8

432 = 3X

144 = X

–4/10 / X-1 = 10 / 45/10

–2/5 / X-1 = 10/ 9/2

–2/5 / X-1 = 10/18

–2/5 / X-1 = 5/9

–18/5 = 5X – 5

–18 = 25X – 25

–18 + 25 / 25 = X

7 / 25 = X

2 ítem.

36/X = X/4

144 = X² /×✔

12 = X

–35/10 / b = b / –14

–7/2 / b = b/–14

–7/2×–14 = b²

98/2 = b²

49 = b² /×✔

7 = X

8/y = y/72

576 = y² /×✔

24 = y

22/10 / m = m / 845/11

11/2 / m = m / 845/11

11/2 × 845/11 = m²

845/2 = m² /×✔

✔845/2 = m

d/5= 80/d

d²= 400 /×✔

d = 20

m/ ½ = 45/10 / m

m² = 45/10 × ½

m² = 9/2 ×1/2

m²= 9/4 /×✔

m= 3/2
