9. 2x² +x - a = 5 ==> 2(0)² +(0)- a = 5 ==> 0 - a = 5 ==> -a=5 ==> a = – 5

___o__o__

10. 2(a²+ab)+3-ab ==> 2a² + 2ab +3 - ab ==> 2a² + ab +3 ==> 2(5)²+ (5)(-3) +3 = 2(25)- 15 +3 = 50-15+3 = 53-15 = 38

Answer:

[tex]\rm x=7[/tex]

Step-by-step explanation:

Given equation:

[tex]\rm 5x-2+x=9+3x+10[/tex]

Collect like terms:

[tex]\implies \rm 5x+x-2=3x+10+9[/tex]

Combine like terms:

[tex]\implies \rm 6x-2=3x+19[/tex]

Add 2 to both sides:

[tex]\rm \implies 6x-2+2=3x+19+2[/tex]

[tex]\rm \implies 6x=3x+21[/tex]

Subtract 3x from both sides:

[tex]\rm \implies 6x-3x=3x+21-3x[/tex]

[tex]\implies \rm 3x=21[/tex]

Divide both sides by 3:

[tex]\implies \rm 3x \div 3=21 \div 3[/tex]

[tex]\implies \rm x=7[/tex]

The type of partnership that is characterized by the limited liability of all partners is the limited liability partnership.

A limited liability partnership has a statutory fund divided into shares, the size of which is determined by the statutory documents, and is liable for obligations only within the limits of its contribution.

The supreme governing body is the Board of Directors. When resolving issues at a meeting of participants, the number of votes is determined in proportion to the size of each participant's share in the statutory fund.

Answer:

21.75 Miles

Step-by-step explanation:

s = d / t

d = s * t

s = 1.75 miles / 2.33333333 minutes

s = 0.75 mile/min

d = 0.75 mile/min * 29 minutes = 21.75 miles

Answer:

The answer is -2.25

Answer:

-2.25

Step-by-step explanation:

1. Between each integer, there are four sections. That means that each section is 1/4, or 0.25

2. Starting at -2, we're going to the left by 0.25 to point B. This can be written as an equation of: [tex]-2 - 0.25 = B[/tex]

3. Now, since -2.25 is the result when subtracting 0.25 from -2, -2.25 is the decimal value positioned at point B.

If a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.

Given the following:

Required:

Actual distance that 8 cm on the map represents.

We would apply our knowledge of proportion to solve this problem as follows:

Let x represent the actual distance we are looking.

6 cm = 8 km

8 cm = x km

[tex]x = \frac{8 \times 8}{6} \\\\x = 10.7 $ km[/tex]

Therefore, if a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.

Answer:

S is the correct answer If it needs to be in alphabetical order.

Step-by-step explanation:

(If not then it could be either S or V)

Answer:

s

Step-by-step explanation:

[tex]s = \frac{t}{v} \\[/tex]

Multiply both sides by v,

s · v = [tex]\frac{t}{v}[/tex] · [tex]\frac{v}{1}[/tex]

The v[tex]s[/tex] on the right hand side cancel each othter out and we are left with

Answer: 2  and 321 or  3  and 214

Step-by-step explanation:

One number is between 200-225.

Now, back up just a bit.  The product of the two numbers is 642.  Product comes from multiplying the two numbers.  So, if we divide 642 by the number that is between 200-225, we will get the other number.

 So, divide 200 into 642 and get 3 with a remainder of 42

     divide 225 into 642 and get 2 with a remainder of 192

This means that the other number must be either 2 or 3.  (note: this is because dividing by 200 gives the biggest value it could be and dividing by 225 gives the lowest value it could be -- think about sharing a bag of candy, dividing it between 2 friends gets each person the most candy and dividing it between more friends (3) gives each person less candy).

Well. if the other number is either 2 or 3, and the product of the two numbers is 642, the numbers must be either: 2  and 321 or  3  and 214

2 other people.

Step-by-step explanation:

First, find a common denominator. Note that what you do to the denominator, you must do to the numerator:

[tex]\frac{1}{4} * \frac{3}{3} = \frac{3}{12}[/tex]

Each other person implies that she will reserve a piece of chocolate for herself, so you will subtract 1:

[tex]\frac{3}{12} - \frac{1}{12} = \frac{2}{12}[/tex]

She will share with 2 other people.
