Solving one step equation x/10=3

Answer:

x = 1

Step-by-step explanation:

[tex] {5}^{2x} - 2( {5}^{x} ) - 15 = 0[/tex]

[tex]( {5}^{x} {)}^{2} - 2 \times {5}^{x} - 15 = 0[/tex]

[tex] {t}^{2} - 2t - 15 = 0[/tex]

[tex] {5}^{x} t = - 3 \: \: .5[/tex]

[tex] {5}^{x} = 5[/tex]

[tex]x = 1[/tex]

£6000 - £3000 = £3000

Answer:

C

Step-by-step explanation:

They are complementary which means they add to 90. I take it that the c is a typo and you meant x

6x + 3 + 4x + 7 = 90                  Combine like terms.

10x + 10 = 90                             Subtract 10 from both sides

10x = 90 - 10

10x = 80                                    Divide by 20

x = 80/10

x = 8

To convert m/s to mi/min we have to find conversion factor first

1 mile = 1609.344 m

1m = 1/1609.344 miles

1 min = 60 s

1s = 1/60 min

Let’s put mi/min instead of m/s according to equations above

m/s = [1/1609.344 miles] / [1/60 min]

The conversion factor is

f = 60 / 1609.344

Now we can convert m/s to mi/min

V (mi/min) = 2.998 ∙ 108 m/s ∙ f = 2.998 ∙ 108 ∙ (60 / 1609.344) = 1.118 ∙ 107 mi/min

Answer: V = 1.118 ∙ 107 mi/min

Hope u have a good day of learning

1 mile = 1609.344 m

1m = 1/1609.344 miles

1 min = 60 s

1s = 1/60 min

Let's put mi/min instead of m/s according to equations above

m/s = [1/1609.344 miles] / [1/60 min]

The conversion factor is

f = 60 / 1609.344

Now we can convert m/s to mi/min

V (mi/min) = 2.998-108 m/s f= 2.998 108 (60/1609.344) = 1.118-107 mi/min

Answer: V = 1.118 - 107 mi/min

Answer:

3rd side = 6x + 3

Step-by-step explanation:

The perimeter must be the given trinomial

The 3rd side = Perimeter - sum of the two given sides.

side 1 = 4x^2 + 2x

side 2 = 3x^2 + 6

Sum = 7x^2 + 2x + 6

3rd side = Perimeter - sum

3rd side = 7x^2 + 8x + 9 - (7x^2 + 2x + 6)        Remove the brackets

3rd side = 7x^2 + 8x + 9 - 7x^2 - 2x - 6

3rd side = 6x + 3

Answer:

  27

Step-by-step explanation:

Evaluating this expression according to the order of operations is a straightforward calculator problem.

  = (81 ÷ 27)³ = 3³ = 27

__

You can also use the rules of exponents to simplify this before evaluating.

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

__

  = ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27

Find the 2 and 7 on the left diagram.

Answer:

(72, 297)

Step-by-step explanation:

1/3v = (-12/3, 15/3) = (-4, 5)

4w = (3(4), 7(4)) = (12, 28)

The sum of these two is (12 - 4, 5 + 28) = (8, 33)

9 times this vector is (8(9), 33(9)) = (72, 297)
