Your starting equation is: x/6 + 4 = 15 The first step would be to subtract 4 from both sides, to move all of the constants to the right side of the equation. x/6 = 11 The final step is to multiply both sides by 6, to get rid of the fraction on the left side of the equation. x = 66 Hope this helps!

\dfrac{x}{6}+4=15 

\dfrac{x}{6}=15-4    <span>Subtract \ 4 \ from \ both \ sides
</span>
\dfrac{x}{6}=11 

x=11*6&#10;&#10; &#10;     Multiply \ both \ sides \ by \ 6 

x=66          Solution

given sin A =3/-/34 and that angle S is in quadrant 1, find the exact value of tan A in simplest radical form using a ration
Vedmedyk [2.9K]

Answer:

\tan(A) = \frac{3}{5}

Step-by-step explanation:

Given

\sin(A) = \frac{3}{\sqrt {34}}

0 \le A \le 90 --- First Quadrant

Required

Find tan(A)

The sin of an angle is:

\tan(A) = \frac{Opposite}{Hypotenuse}

and

\sin(A) = \frac{3}{\sqrt {34}}

By comparison:

Opposite = 3

Hypotenuse = \sqrt{34

So, the Adjacent is:

Hypotenuse^2 = Adjacent^2 + Opposite^2

(\sqrt{34})^2 = Adjacent^2 + 3^2

34 = Adjacent^2 + 9

Collect like terms

Adjacent^2 =34 - 9

Adjacent^2 =25

Take square roots

Adjacent =\sqrt{25

Adjacent =5

The tangent of an angle is:

\tan(A) = \frac{Opposite}{Adjacent}

This gives:

\tan(A) = \frac{3}{5}

Serial numbers for a product are to be made using 2 letters followed by 3 numbers. If the letters are to be taken from the first
Daniel [21]
2 Letters chosen among 6 with no repeat:
a) the first has 6 ways
    the second has 5  ways

Then to choose 2 letters among 6, with no repeat, there are 6x5 = 30 ways

 b) 3 numbers are taken from the digits 0 through 9 with repeats (total = 10)
     the first has 10 ways
     the second has 10  ways
    the third has 10  ways

Then to choose 3 numbers among 10, with repeat, there are 10x10x10= 1000 ways
And the total serial numbers that can be generated is
30 x 1000 = 3000

Sholpan [36]

Answer:

A.

Step-by-step explanation:

So we are given the function:

f(x)=7x+8

To find the inverse of the function, we simply need to flip <em>f(x)</em> and <em>x</em> and then solve for <em>f(x)</em>. Thus:

x=7f^{-1}(x)+8\\x-8=7f^{-1}(x)\\f^{-1}(x)=\frac{x-8}{7}

So the answer is A.
