What is the value of x in the equation 1/4x+2=-5/8x-5

x= -8

Step-by-step explanation:

1/4 x + 2 = -5x/8 - 5

x/4 + 2 = -5x / 8 - 5

we collect like term

x/4 + 5x / 8 = -5 - 2

2x + 5x / 8 = -7

7x / 8 = -7

cross multiply

7x = -56

Divide bothside by 7

7x / 7 = -56/7

x = -8

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
