Answer:

x=36

Step-by-step explanation:

So, lets go over what we know:

16 is equal to 4/9ths of x.

As a equation, this looks like:

16 = \frac{4}{9}x

We can begin to solve for x by multiplying both sides by the denominator, 9, which gets us:

16*9 = 4x

=

144 = 4x

Then we can divide by the coefficent of x, which is 4, to get our answer:

\frac{144}{4} = x

=

36=x

This is our answer! Hope this helps! :3

TEA [102]

Answer:

Step-by-step explanation:

given,

a) √x + 6 = 4                                                    

to solve the above equation subtract both side with 6

    √x + 6 - 6  = 4 - 6                  

                √x  = -2                  

squaring both side

                (√x)² = (-2)²              

                       x = 4            

a) ∛x + 6 = 4                                            

to solve the above equation subtract both side with 6

    ∛x + 6 - 6  = 4 - 6

                ∛x  = -2

cubing  both side

                (√x)³ = (-2)³

                      x = -8

Which equation can be used to solve for the measure of angle abc? tan(x) = startfraction 2.4 over 10 endfraction tan(x) = startf
Len [333]

The equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3

<h3 /><h3>SOH CAH TOA identity</h3>

The identity is used to find the measure of sides and acute angles of a right triangle

From the diagram shown, <ABC is the reference abgle hence;

Opposite side = 2,4cm

Hypotenuse .=10.3cm

According to the identity

sin x = opp/hyp

sinx = 2.4/10.3
sinx = 0.233

x =  13.47 degrees

Hence the equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3
