Answer:

[tex] \boxed{ \tt{1. \: \: 9a + 2b}}[/tex]

[tex] \boxed{ \tt{2. \: \: 2pqr + 3qrs - 3pqr}}[/tex]

Step-by-step explanation:

[tex] \tt{1. \: \: (5a - 6b) + (4a + 8b)}[/tex]

Remove the unnecessary parentheses :

⇾ [tex] \tt{5a - 6b + 4a + 8b}[/tex]

Combine like terms. Like terms are those which have the same base { For instance : In the term 4a , a is the base }. Also remember that : Only coefficients of like terms can be added or subtracted.

⇾ [tex] \tt{5a + 4a - 6b + 8b}[/tex]

⇾ [tex] \tt{9a + 2b}[/tex]

[tex] \tt{2. \: \: pqr + pqr - 2qrs + 5qrs - 3pqr}[/tex]

Combine like terms :

⇾ [tex] \tt{2pqr + 3qrs - 3pqr}[/tex]

Answer:

1. (5a-6b) + (4a+8b)

= (5a + 4a) + (8b - 6b)

=9a + 2b

2. pqr+pqr-2qrs+5qrs-3pqr

= 2pqr-3qrs-3pqr

= -3qrs-pqr

Answer:

a = -66

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

13 + a/11 = 7

Step 2: Solve for a

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Here we see that 7 does indeed equal 7.

∴ a = -66 is the solution to the equation.

Answer:

If you mean [tex]\frac{13+a}{7}=7[/tex] then the answer is [tex]a=36[/tex].

If you mean [tex]13+\frac{a}{7} =7[/tex] then the answer is [tex]a=-42[/tex].

Step-by-step explanation:

To do this question, you simplify both sides of the equation and then isolate the variable.

Answer:

c⁶/d²

Step-by-step explanation:

a⁻ⁿ = 1/aⁿ

So :

c⁶d⁻² = c⁶/d²

Answer:

It is impossible for us to answer that question as we weren't provided with a text to analyze.

Step-by-step explanation:

Given:

The equation is

[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]

To find:

The length of the line segment AC.

Solution:

We have,

[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]

[tex]1.428148=\dfrac{15}{b}[/tex]

Multiply both sides by b.

[tex]1.428148b=15[/tex]

Divide both sides by 1.428148.

[tex]b=\dfrac{15}{1.428148}[/tex]

[tex]b=10.50311[/tex]

[tex]b\approx 10.503[/tex]

In a triangle ABC, the line of line segment AC is b. So,

[tex]AC\approx 10.503[/tex]

Therefore, the length of the line segment AC is 10.503 units.

Answer:

6.7234724... ; ✓7

Step-by-step explanation:

In the most simplest of terms, we can explain irrational numbers as numbers which cannot be expressed as a ratio of two integers usually because they cannot give an exact value when evaluated.

Using the values given :

6.7234724... - - >This is an irrational number because the '...' depicts that the values are unending and as such an exact expression in the form of a ratio (p/q) cannot be determined.

315, 26, 17, 8 - - - > Is a rational number, it could be express in ratio form as : 315/1. 315 is an integer and all integers are rational.

-0.25 - - > it could be expressed as - 1 /4. Hence it is a rational number.

✓7 - irrational as the simplification gives : 2.6457513...

Answer:

In step one, -8 - 2 should result in -10, not -6.

Answer:

(d)

Step-by-step explanation:

._. its d in my opinion most sense to me

Answer:

The answer is 96%.

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 55 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 55, so we can write it down as 100%=55.

4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.

5. Now we have two simple equations:

1) 100%=55

2) x%=52.8

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=55/52.8

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52.8 is what percent of 55

100%/x%=55/52.8

(100/x)*x=(55/52.8)*x       - we multiply both sides of the equation by x

100=1.0416666666667*x       - we divide both sides of the equation by (1.0416666666667) to get x

100/1.0416666666667=x

96=x

x=96

now we have:

52.8 is 96% of 55

Answer:

  A.  d = 0 -- one (1) solution

  B.  x = {1, 3.5}

Step-by-step explanation:

A. The discriminant for ax²+bx+c = 0 is ...

  d = b² -4ac

For the given equation, this is ...

  d = (-36)² -4(9)(36) = 0

The discriminant is zero (0).

The discriminant divided by the leading coefficient (a=2) will give the difference between the two roots of the equation. When the difference is zero, as here, both roots are the same. Effectively, there is one (1) solution to the equation.

__

B. The equation can be factored as ...

  2x² -9x +7 = (2x -7)(x -1) = 0

The solutions are the values of x that make the factors be zero:

  2x -7 = 0  ⇒  x = 7/2

  x -1 = 0  ⇒  x = 1

  The solutions are x = 7/2  or  x = 1.
