Question

1. En el espacio dado, escriba los términos que hacen verdadera la igualdad:
a) _× (-7) = -42
b) 18 ÷ _ _ = -3
c) 9 × _ = -45
d) _÷ (-5) = 6
e) (-3) × (-5) ×_ _ = 4

Answer 1

El espacio sea "x".

A. x × (-7) = -42

x × (-7) = -42

-7x = -42

x = 6

B. 18 ÷ x = -3

18 ÷ x = -3

18/x = -3

18 = -3x

-3x = 18

x = -6

C. 9 × x = -45

9 × x = -45

9x = -45

9x ÷ 9 = -45 ÷ 9

x = -5

D. x ÷ (-5) = 6

x ÷ (-5) = 6

-1/5x = 6

x = -30

E) (-3) × (-5) × x = 4

(-3) × (-5) × x = 4

15 = 4

x = 4/15
