When working with decimals it is important to remember the order after the decimal point. For instance in .0 the zero is in the tenth position, in .01 the one is in the hundreth position. As you can see the first point is 10 the second is 10 x 10 this continues on as each new number is multiplied...

The first thing that you will want to do is write the equation 91+82+83+92+x=y in this x represents the final exam and y is the final average since th final average is given to us as 90 the easiest way to find out what the final exam score is now is to multiply 90 x 5= 450...

When you think of a problem such as this 5x<3x you have to view the entire range of numbers. There is no positive number multiplied by 5 that is less than the same number multiplied by 3; however, if the variable which is the x is a negative number the equation becomes true, For instance: 5(-1)<3(-1)=...

There is no z in the equation you used as an example so that would not be the answer. With this kind of problem you will use the distributive property and 7 will be multiplied by everything in the parenthesis as such  7(b+3)=7b+21 I hope this helps you

The thing you want to do for this type of equation is find the result for each variable which is the letter that will make it equal to the other. The easiest way is to substitute a number for one of the variables for instance.  3(2-5)=2(a+5) for this we substitute the 2 for the q now...

The first thing you need is the formula for calculating distance. d=rt which is distance=rate*time You then will want to create a table so that you can plug in the information like such:                Distance =  Rate  * Time Sheila  ...

Hi the steps take a couple of minutes but this should help you.  In A1 enter the date and time you want to finish your project  In A2: =now() In A3: ="Months " & DATEDIF(A2,A1,"m") In A4: =" Days " & DATEDIF(A2,A1,"md") In...

Anytime you have one thing equal to another it is considered an equation for example x=1 2+3=5 a+b=c These are all considered equations if it is stacked it is the exact samething only written a different way. Hope this helps you.

Any line parallel to another will have the same slop. Since the slope of the x axis is 0 the slope of the other line will be 0 as well and written as  y= -6 which indicates that the line is parallel to the x axis and 6 units below it.

For the problem you put up you would simply add the numbers together and keep the g after it  12g+7g=19g  I hope this helps.

The thing that you need to do is order of operations so that it becomes easier to work with. For the first problem  a = 8x5^2 -(3x4)^2 +7x2^3 get rid of the parenthesis parts first so: a=8x5^2-12^2+7x2^2 then work on the squared part a=8x25-144+7x8 remember that a negative...
