-6(10-4f) = -3(-12-8f)

Mathematics
1 answer:
Fynjy0 [20]3 years ago
7 0

Answer:

no solution

Step-by-step explanation:

Given

- 6(10 - 4f) = - 3(- 12 - 8f) ← distribute parenthesis on both sides

- 60 + 24f = 36 + 24f ( add 60 to both sides )

24f = 96 + 24f ( subtract 24f from both sides )

0 = 96 ← not possible

This indicates the equation has no solution

Desiree writes songs for her band her first song is 3 1/2 minutes long her second song is one 1/2 times as long as her first son
vesna_86 [32]

Answer:Number of minutes of second  Song = 5 1/4 minutes

Number of minutes of third   Song =3 1/2  minutes

Step-by-step explanation:

Number of minutes of First Song = 3 1/2 minutes

Number of minutes of second  Song = one 1/2 times as long as her first

= 1 1/2 X 3 1/2 minutes

3/2 X 7/2

21/4 = 5 1/4 minutes

Number of minutes of third   Song = 2/3 times as long as her second song

2/ 3 x 5 1/4

= 2/3 x 21/4 =42/12

Dividing the numerator and denominator by 3 to reduce the fraction

42/ 12 / 3/3 = 14/4

14/4 = 3 2/4 = 3 1/2  minutes

Which of the following is equivalent to (125^2/ 125^4/3)
zysi [14]

Option D:

The expression equivalent to the given expression is 25.

Solution:

The image of the question is attached below.

Given expression:

$\left(\frac{125^{2}}{125^{\frac{4}{3}}}\right)

To find which expression is equivalent to the given expression:

$\left(\frac{125^{2}}{125^{\frac{4}{3}}}\right)

125 can be written as 5 × 5 × 5 = 5³

      $=\frac{(5^3)^{2}}{(5^3)^{\frac{4}{3}}}

Using the exponent rule: \left(a^{m}\right)^{n}=a^{(m n)}

     $=\frac{5^6}{5^{\frac{12}{3}}}

     $=\frac{5^6}{5^4}

Using the exponent rule: \frac{a^{m}}{a^{n}}=a^{m-n}

      =5^{(6-4)}

      = 5²

      = 25

$\left(\frac{125^{2}}{125^{\frac{4}{3}}}\right)=25

The expression equivalent to the given expression is 25.

Option D is the correct answer.
