Question

find x such that:-
(i) -1/5 = 8/x
(ii) 7/-3 = x/6
(iii) 3/5 = x/-25
(iv) 13/6 = -65/x
(v) -48/x = 2 ​

Answer 1

Answer:

1) -40

2) -14

3) -15

4) -30

5) -0.041

Step-by-step explanation:

1) -1/5=8/x

-1x=8×5

-x=40

or x= -40

2) 7/-3=x/6

7×6= -3x

42= -3x

x= -42/3

x= -14

3) 3/5=x/-25

3×-25=5x

-75=5x

x= -75/5

x= -15

4) 13/6= -65/x

13x = -65×6

x= -390/13

x = -30

5) -48/x= 2

-48 =2x

x= -2/48

x = -1/24

or x= -0.041
