Solve and find X. Question says 5-x / 2 = 2x-7

Mathematics
2 answers:
poizon [28]2 years ago

Answer:

x = 3.8

Step-by-step explanation:

The equation is (5 - x) / 2 = 2x - 7

Multiply both sides by 2:

5 - x = 4x - 14

Add 14 to both sides:

19 - x = 4x

Add x to both sides:

19 = 5x

Divide both sides by 5 to isolate x:

3.8 = x

Therefore, x = 3.8.

Simplify. Assume that no denominator is equal to zero. ([3^2]^3g^3h^4)^2
mariarad [96]

Answer:

531,441·g^6·h^8

Step-by-step explanation:

The operative rule of exponents is ...

(a^b)^c = a^(b·c)

Working from the inside out, according to the order of operations, we get ...

= (9^3·g^3·h^4)^2

= 729^2·g^(3·2)·h^(4·2)

= 531,441·g^6·h^8

Determine the slope of the line that has the following coordinates: (5, 9)(11, - 3)
AlladinOne [14]

Answer:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =\frac{y_2 -y_1}{x_2 -x_1}

And replacing we got:

m =\frac{-3 -9}{11-5}= -2

And the best answer for this case would be :

m=-2

Step-by-step explanation:

For this case we have the following two points given:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =\frac{y_2 -y_1}{x_2 -x_1}

And replacing we got:

m =\frac{-3 -9}{11-5}= -2

And the best answer for this case would be :

m=-2

a positive number is 7 times another number if 3 is added to both the numbers then one of the new number becomes 5 by 2 times th
Neko [114]

Answer:

7 and 1

Step-by-step explanation:

Let the numbers be a and b.

<u>A positive number is 7 times another number:</u>

  • a = 7b

<u>If 3 is added to both the numbers then one of the new number becomes 5 by 2 times the other new number:</u>

  • a+3 = 5/2 × (b +3)

<u>To solve this we substitute </u><u>a</u><u> with </u><u>7b</u><u> in the second equation:</u>

  • 7b + 3 = 5/2 × (b +3)               ⇒ multiplying both sides by 2
  • 14b + 6 = 5b + 15                    ⇒ collecting like terms
  • 14b - 5b = 15 - 6
  • 9b = 9
  • b = 1                                        ⇒ solved for b

<u>Then, finding a:</u>

  • a= 7b
  • a=7*1
  • a= 7                                        ⇒ solved for a

<u>So the numbers are</u> 7 and 1
