Answer:

When solving equations like this, you have to use a method called PEMDAS.

This stands for:

<h3>P- Parentesis</h3><h3>E- Exponents</h3><h3>M- Multiply</h3><h3>D- Divide</h3><h3>A- Addition</h3><h3>S- Subtraction</h3>

(7x + 5) - (3x +2)

Let's work it out...

Step one) Distribute the equation

Distributing the equation helps simplify it and make solving much easier.

(7x−5) − 1(3x−2)

(7x−5) − 3x + 2

Step two) Eliminate the Parenthesis

Now that the equation is simplified, you can take out the Parenthesis.

(7x − 5) − 3x + 2

7x − 5 − 3x + 2

Step three: Add the numbers

Add the two whole numbers together (-5 + 2)

7x − 5 − 3x + 2

7x − 3 − 3x

Step four: Combine like terms

Combine like terms or the numbers with variables (7x - 3x)

7x − 3 − 3x

4x − 3

Solution

<h2>4x - 3</h2>

Hope this helped! :)

Answer:

x = 0.75

Step-by-step explanation:

Simplifying

(7x + -5) + -1(3x + -2) = 0

Reorder the terms:

(-5 + 7x) + -1(3x + -2) = 0

Remove parenthesis around (-5 + 7x)

-5 + 7x + -1(3x + -2) = 0

Reorder the terms:

-5 + 7x + -1(-2 + 3x) = 0

-5 + 7x + (-2 * -1 + 3x * -1) = 0

-5 + 7x + (2 + -3x) = 0

Reorder the terms:

-5 + 2 + 7x + -3x = 0

Combine like terms: -5 + 2 = -3

-3 + 7x + -3x = 0

Combine like terms: 7x + -3x = 4x

-3 + 4x = 0

Solving

-3 + 4x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 4x = 0 + 3

Combine like terms: -3 + 3 = 0

0 + 4x = 0 + 3

4x = 0 + 3

Combine like terms: 0 + 3 = 3

4x = 3

Divide each side by '4'.

x = 0.75

Simplifying

x = 0.75

The product of w and 2 is greater than or equal to 19.
madam [21]

Equation Form:

w x 2 \geq 19

Divide both sides by 2:

w \geq 9.5

So, w must be equal to or greater than 9.5 for this equation to work.

Use the following regression results to answer the remaining questions. Y measures average hourly earnings AHE in U.S. dollars f
Ulleksa [173]

Answer:

Check the explanation

Step-by-step explanation:

Y = 11.5 + 4.5*X1 -2.5*X2 +0.7*X3+1.6*X4 -2.4*X5 -2.8*X6

FOR JANE

X1 =1 , X2 =1 , X3 =5 , X4 =0 ,X5=0, X6=1

SO,

Y =11.5+(4.5*1)-(2.5*1)+(0.7*5)+0+0-(2.8*1)

= 14.2

..........................

FOR Sophie

X1 =1 , X2 =1 , X3 =10 , X4 =1 ,X5=0, X6=0

so,

Y =11.5+(4.5*1)-(2.5*1)+(0.7*10)+ (1.6*1)+0+0

= 22.1
