darren has 3/4 of a gallon of soil.he needs to plant 5 small plants.if he splits the soil evenly between the plants.how much soi

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.

Simplify the expression. Write your answer using only positive exponents. Evaluate any numerical powers.

gtnhenbr [62]

Answer:

9x⁵

Step-by-step explanation:

Use properties of exponents:

$a^{b} a^{c} = a^{b+c}$ , $(a^{b} ^)^{c} = a^{bc}$ , $1/a^{-b} = a^{b}$

Simplify the given expression:

3⁴⋅x⋅(3/x²)⁻² =
3⁴·x·(3x⁻²)⁻² =
3⁴·x·(3⁻²)(x⁻²ˣ⁻²) =
3⁴⁻²·x¹⁺4 =
3²·x⁵ =
9x⁵

The sum of three consecutive even integers is 36. Let x represent the first integer, x + 2 represent the second integer, and x +

prisoha [69]

Let

x------> the first even integer

x+2---->the second even integer

x+3---->the third even integer

we know that

$x+(x+2)+(x+4)=36$ -----> equation that represent the situation

solve for x

Combine like terms in the left side

$(x+x+x)+(2+4)=36$

$3x+6=36$

therefore

the answer is the option B

$3x+6=36$
