Answer:

X = 14

Step-by-step explanation:

3(2x+6) = 2(4x-5)

you will need to multiply the outside number to the numbers in the parentheses so now it's: ( I reordered the terms to give you a heads up)

6x + 18 = 8x - 10

Reordered:

18 + 6x = -10 + 8x

Now let's solve for X

18 + 6x = -10 + 8x

Now combine like terms

18 + -2x = -10

Now subtract 18 to get -2x alone

18 + -2x = -10

-18 -18

Now it's:

-2x = -28

Now divide by -2 to get x alone

-2x = -28

/-2 /-2

And now it's:

X = 14

Which expressions are equivalent to 1.08^4t?

artcher [175]

Answer:

Therefore,

The Equivalent expression is option A,

$(1.08^{4})^{t}$

Step-by-step explanation:

Given:

Expressions is

$1.08^{4t}$

To Find:

Equivalent expression ?

Solution:

We have Law of indices

$(a^{x})^{y}=a^{x\times y}\\(a^{\frac {x}{y}})^{z}=a^{\frac{x\times z}{y}$

For option A

(1.08^t)^4

$(1.08^{4})^{t}=1.08^{4t}$

Hence option A is the Equivalent expression.

For option B

1.08^8t/1.08^2t

$(1.08^{\frac{8t}{1.08}})^{2t}=1.08^{\frac{16t^{2}}{1.08}}=1.08^{14.81t^{2}}$

Which is not the Equivalent expression.

For option C

1.08^4*1.08^t

$(1.08^{4\times 1.08})^{t}=1.08^{4.32t}$

Which is not the Equivalent expression.

For option D

1.08^6t/1.08^2t

$(1.08^{\frac{6t}{1.08}})^{2t}=1.08^{11.11t^{2}}$

Which is not the Equivalent expression.

Therefore,

The Equivalent expression is option A,

$(1.08^{4})^{t}$
