Question

ayudaaaaaaaaaaaaaaaaaaa

Answer 1

Explicación paso a paso:

1.

a) ⅕x = 3 / X = 15

⅕x × 5 = 3 × 5

X = 15

b) x/8 = –6 / X = –48

x/8 × 8 = –6 × 8

X = –48

c) –1/10x = 5 / x = –50

–1/10x × –10 = 5 × –10

X = –50

2.

a) 1/7X = 4 》》 X = 7×4 》》 X = 28

b) X/9 = –2 》》 X = 9×–2 》》 X = –18

c) –x/3 = 5 》》 X = –3×5 》》 X = –15

d) –X/4 = –5 /×-1》》 X = 4×5 》》 X = 20

e) X/6 = –6 》》 X = 6×–6 》》 X = –36

f) –x/10 = 3 》》 X = 3×–10 》》 X = –30
