you need to do 10-6 is 4 then 2x? is 4

Answer:

(5 x + 1) - (-10 x + 6)

5x +1 + 10x - 6

25x - 5

Step-by-step explanation:

(x - 2) - (6x - 9)

x - 2 - 6x + 9 =

-5x +7

(5 x + 1) - (-10 x + 6)

5x +1 + 10x - 6

25x - 5

-4 x + 2 x + 7 - 3 x

-5x + 7

(4 x + 3) + (-9 x + 4)

4x +3 -9x + 4

-5x + 7

The Expression which not gives (-5x+ 7) is  (5 x + 1) - (-10 x + 6).

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

1. (x - 2) - (6x - 9)

= x - 2 - 6x + 9

= -5x +7

2. (5 x + 1) - (-10 x + 6)

= 5x +1 + 10x - 6

= 25x - 5

3. -4 x + 2 x + 7 - 3 x

= -5x + 7

4. (4 x + 3) + (-9 x + 4)

= 4x +3 -9x + 4

= -5x + 7

Answer:

the rate of change is 2 because it's had the variable

Given:

Professional climbers climb 828 meters in 6 hours.

To find:

how far did they climb in the first 2 hours?

Solution:

According to the question,

In 6 hours, they climb 828 meters.

In 1 hour, they climb [tex]\dfrac{828}{6}[/tex] meters.

In 2 hour, they climb [tex]2\times \dfrac{828}{6}[/tex] meters.

Now, the distance they climb in the first 2 hours is

[tex]\text{Climb in first two hours}=2\times \dfrac{828}{6}[/tex]

                                      [tex]=\dfrac{828}{3}[/tex]

                                      [tex]=276[/tex]

Therefore, they will climb 276 meters in first 2 hours.

Answer:

the value of these two numbers are 1/2 and 3/2

Step-by-step explanation:

Given that:

x+y < 2 ---- (1)

y - x > 1 ---- (2)

From equation (2), let y  > 1 + x then substitute it into equation (1)

x + 1 + x < 2

2x + 1 < 2

2x < 2 - 1

2x < 1

x < 1/2

From equation (2), replace the value of x to be 1/2

y - 1/2 > 1

y > 1 + 1/2

y > 3/2

Commission percent = 3 % (Approx)

Step-by-step explanation:

Given:

Amount of commission = $500

Sales price of car = $17,250

Find:

Commission percent

Computation:

Commission percent = [Amount of commission/Sales price of car]100

Commission percent = [500/17,250]100

Commission percent = 2.89 %

Commission percent = 3 % (Approx)

x = [tex]\sqrt{30}[/tex]

Step-by-step explanation:

Applying altitude- on - hypotenuse theorem.

(leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )

x² = 3 × (3 + 7) = 3 × 10 = 30 ( take square root of both sides )

x = [tex]\sqrt{30}[/tex]

Answer:

DFE = 23

EDS = 111

Step-by-step explanation:

Mathematically;

(3x-10) + 46 + 180 - (5x + 14) = 180

Reason for this is that sum of angles in a triangle is 180

Thus;

3x-10 + 46 - 5x-14 = 0

-2x + 22 = 0

2x = 22

x = 22/2 = 11

DFE = 3x - 10 = 3(11) - 10 = 33-10 = 23

EDS = 180 - (5x + 14) (sum of angles on a straight line)

180 - (5(11) + 14)

= 180 - 69

= 111

EDS

Step-by-step explanation:

   The given values are;

          [tex]\frac{5}{6}[/tex]   and  [tex]\frac{10}{12}[/tex]  

   [tex]\frac{10}{12}[/tex]  ,

    reducing to the smallest term by dividing by 2;

       is   [tex]\frac{5}{6}[/tex]  

So;

  [tex]\frac{5}{6}[/tex]   and  [tex]\frac{10}{12}[/tex]   are both like fractions.
