Jada solved the equation Negative StartFraction 4 over 9 EndFraction = StartFraction x over 108 EndFraction for x using the step
aleksandr82 [10.1K]

Answer:

Jada error was he multiplied the equation by (-9/4) to make the coefficient of x one. He should have multiplied it by 108

Step-by-step explanation:

Jada solved the equation

-4/9 = x/108

using the steps below:

-4/9 = x/108

(-4/9)(-9/4) = (x/108)(-9/4)

x = -1/48

Jada should have multiplied through by 108, instead of (-4/9). That was the error he made.

Multiplying through by 108 gives

(-4/9)(108) = (x/108)(108)

-48 = x

x = -48

The answer should have been

x = -48

and not

x = -1/48

nika2105 [10]

Number of plants = 5

Amount of soil present for 5 plants = 3/4 gallons

Now here we have to find how much soil will each plant get.

So we have to apply unitary method here to find how much would each plant get the share of soil.

Soil required by 5 plants = 3/4 gallons

Soil required by 1 plant = 3/4 divided by 5 = 3/20 gallons

Answer: Each plant will get 3/20 gallons of soil.
