Soil that contains 30% clay is added to soil that contains 70% clay to create 10 gallons of soil containing 50% clay. How much of each of the soils was combined?

5 gallons of soil that contains 30% clay and 5 gallons of soil that contains 70% clay is combined

Step-by-step explanation:

Given:

Soil that contains 30% clay is added to soil that contains 70% clay to create 10 gallons of soil containing 50% clay.

Now, to find the quantity of each of the soils was combined.

Total quantity of soil  containing 50% clay = 10 gallons.

Let the quantity of soil that contains 30% clay be

And let the quantity of soil that contains 70% clay be

Now, to get the quantity of soils:

Subtracting both sides by 7 we get:

Dividing both sides by -0.4 we get:

The quantity of soil that contains 30% clay = 5 gallons.

Now, substituting the value of we get:

The quantity of soil that contains 70% clay = 5 gallons.

Therefore, 5 gallons of soil that contains 30% clay and 5 gallons of soil that contains 70% clay is combined.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
