Y - 0.8x = 0.5

Sveta_85 [38]

Answer:

$y=\frac{5+8x}{10} , x=x$

Step-by-step explanation:

y-0.8x=0.5

y*10-0.8x*10=0.5*10

10y-8x=5

10y-8x+8x=5+8x

10y/10=5/10+8x/10

y=5+8x/10

5*5+8x/10-2.5

8x+5/2-2.5=4x

y=5+8x/10, x=x

Please help and dont just say hope you get it

Llana [10]

Answer:

X = 10 Y = 14

Step-by-step explanation:

Okay, so. If you divide the Y and X for example 2.8 divided by 2 is 1.4 5.6 divided by 4 is 1.4. So like it says it is proportional. So, when you get down to the eight. You can see they are adding the X by 2 so the X is 2. The Y would be 2.8. So, you would add 2.8 into 11.2. That would be 14.

Hope this helps!
