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:

$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

x=6

MKL=37

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. because U is between T and B

TU +UB = TB

2x+3x+1 =21

5x = 20

x= 4

mTU = 2x = 2*4 = 8

mUB = 3x+1 = 3*4 +1 = 12 +1 = 13

2.

m∠JKL = 59°

m∠MKL + m∠JKM = m∠JKL

5x+7 +2x+10 = 59

7x +17 = 59

7x = 59-17

x = 42/7 = 6

m∠MKL=5x+7 = 5*6 +7 = 30+7 = 37°

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:

12:24 = 1:2

Step-by-step explanation:

Since there are 12 multiplication problems, and 24 division problems, the ratio of multiplication and division problems are 12:24, now we need to put it in simplest form.

We need to find the highest number of which both are divisible by, 12 and 24 are both divisible by 12.

So 12÷12 = 1, and 24÷12 = 2, so 12:24 in simplest form is 1/2 or 1:2.

Answer:

1/2

Step-by-step explanation:

12 is half of 24. Therefore, the answer as a fraction in simplest form is 1/2.

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.
