Answer:

$1.96

Step-by-step explanation:

Let's set up a proportion:

1 lb : $4.25 = 0.46 lb : $x

Here, x is the cost of 0.46 pounds. The ratio above can also be written in fraction form as:

[tex]\frac{1}{4.25} =\frac{0.46}{x}[/tex]

Now, we cross-multiply:

1 * x = 4.25 * 0.46

x = 1.955 ≈ $1.96

Answer:

Father age= 52 years

Son age =8 years

Step-by-step explanation:

Given:

⇒ Sum of ages of father and his son = 60 years

⇒ After 14 years - father's age will be 3 times the age of his Son

⇒ Find their present ages

Solution:

According to the given,

The total = 60

Father age = "x " ( unknown)

Son age = 60 - x

In additionally,

Father age = ( x + 14 ) years

Son age = ( 60 - x + 14 )

= ( 74 - x ) years

Setting up the problem:

x + 14 = 3 ( 74 - x )

Removing parentheses:

x + 14 = 3 × 74 - x

Multiply:

x + 14 = 222 - 3x

variable on one side and the other on other side:

x + 3x = 222 - 14

Add/Subtract:

4x = 208

Divide:

4x/4 = 208/4

x = 52

Hence, at present:

Father age = 52

Son age = 60 - 52

→ 8

As a result,

Their present ages:

Father = 52

Son = 8

Answer:d

Step-by-step explanation:

The money Emily needs to earn to meet her goal if, Emily wants to earn $100 is 20 (5 - d).

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

Given:

Emily wants to earn $100,

She averages 4 buckets per day, and she has already picked blueberries for 5 days,

Calculate the total money earned by Emily till now as shown below,

d × 5 × 4 = 20d

Money left = 100 - 20d

Write the expression as shown below,

The money she needs to earn to meet her goal = 100 - 20d

The money she needs to earn to meet her goal = 20 (5 - d)

Answer:

[tex]x-3y=21[/tex]

Step-by-step explanation:

The standard form of a linear equation is [tex]Ax+By=C[/tex]

STEP 1: Multiply both sides by [tex]3[/tex].

STEP 2: Simplify [tex]3(y+6).[/tex]

STEP 3: Simplify again.

STEP 4: Rewrite the equation with the sides flipped.

STEP 5: Move all terms containing variables to the left side of the equation.

STEP 6: Move all terms not containing a variable to the right side of the equation.

Rearranging the equation given to conform with the standard form of an equation, the expression becomes -x + 3y = - 21

The standard form of expression a linear equation is given as :

Given the expression : y + 6 = 1/3(x - 3)

Multiply both sides by 3

3(y + 6) = x - 3

3y + 18 = x - 3

Move x and y to the same side and the constant to the other.

3y - x = - 3 - 18

-x + 3y = - 21

Hence, the standard form of the equation is - x + 3y = - 21

Answer:

3 + 2√(2)

Step-by-step explanation:

Since the larger plot is 1²m greater than the smaller one.

Let x denote the length of the smaller one, this implies that the larger would be x + 1.

Since the combined length is 3 + 2√(2) we have:

x + (x + 1) = 3 + 2√(2)

2x + 1 = 3 + 2√(2)

2x = 2 + 2√(2)

x = 1 + √(2)

This is the length of the smaller plot. It's area would therefore be:

x² = [1 + √(2)]² = 1 + 2√(2) + 2 = 3 + 2√(2)

Answer:

x = -1.5, -1, 2.

Step-by-step explanation:

I am assuming you want to solve this>

Solve 2x ³ + x ² -7x - 6​ = 0

It looks like x = -1 is a solution so we try it:

2*(-1)^3 + (-1)^2 -7(-1) - 6

= -2 + 1 + 7 - 6

= -1 + 1 = 0

So x = -1 is one root.

So (x + 1) must be a factor of P(x)

Now we divide by x + 1:

x + 1)2x ³     + x ²   -7x -  6​( 2x^2 - x - 6  <--- quotient

       2x^3 + 2x^2

                  -x^2  - 7x

                  -x^2  -  x

                             -6x -  6

                             -6x -  6

                              ----------

2x^2 - x - 6 = 0

(2x + 3)(x - 2) = 0

x = -1.5, 2.
