Answer:

Both are correct.

A) A decimal fraction

B) A common fraction

Step-by-step explanation:

<u>1 step.</u> Write down 0.4 divided by 1:

\dfrac{0.4}{1}.

<u>2 step.</u> Multiply both top and bottom by 10 (because there are 1 digit after the decimal point):

\dfrac{0.4}{1}=\dfrac{0.4\cdot 10}{1\cdot 10}=\dfrac{4}{10}.

This fraction is called a decimal fraction.

<u>3 step.</u> Simplify the decimal fraction:

\dfrac{4}{10}=\dfrac{2\cdot 2}{2\cdot 5}=\dfrac{2}{5}.

This fraction is called a common fraction.

If you rearrange the equation so w is the independent variable, then what is u?<br><br> -2u+6w=9
Serjik [45]

Answer:

u  = - ( 9-6w)/2

Step-by-step explanation:

to  evaluate for u in the expression -2u+6w=9 is simply to look for a way such that we would express u in terms of w and other variables.

solution

-2u+6w=9

-2u = 9 - 6w

divide both sides by the coefficient of u which is -2

-2u/u = 9 - 6w/-2

u  = - ( 9-6w)/2

therefore the value of u when rearranged in the equation -2u+6w=9 is evaluated to be equals to

u  = - ( 9-6w)/2

14. Write a two-column proof.
scZoUnD [109]

Given:

\bold{ 8x=4y-20} \\\\ \bold{ y=13}

Prove:

\bold{x=4}

Solution:

\to \bold{8x=4y-20}..........(i)\\\\\to \bold{ y=13}........................(ii)

Putting the value of equation (ii) into the equation (i):

\to \bold{8x=4(13)-20}\\\\\to \bold{8x=52-20}\\\\\to \bold{8x=32}\\\\\to \bold{x=\frac{32}{8}}\\\\\to \bold{x= 4}\\\\

putting the value x into the equation (i):

\to \bold{8(4)=4y-20}\\\\\to \bold{32=4y-20}\\\\\to \bold{32+20=4y}\\\\\to \bold{52=4y}\\\\\to \bold{y=\frac{54}{4}}\\\\\to \bold{ y= 13.5}

Therefore, the value of x= 4
