Answer: X and Y are variables which means they represent some number that you don't know. When you are working with Graphs, X and Y could be coordinates. When it wants you to solve for x you have to do the inverse opperation until you isolate the variable you are trying to solve. Basically, inverse opperations are if it is -30 on one side you would add 30 to both sides to cancel it out. When you isolate the variable it is only that one letter with everything else on the other side.

Step-by-step explanation:

If this is confusing, let me know an example question and I can help you in the comments.

Find the difference between the fastest girls time and the slowest girl time. Barbra ran 3 3/10, Donna ran 2 4/5 , Cindy ran 4 3
Xelga [282]

Answer: 2.5 or 2 1/2

Step-by-step explanation:

You can convert the mixed fractions to decimal numbers:

- Divide the numerator by the denominator of the fraction.

- Add the result to the whole number.

Thenyou have:

Barbara's time: 3\ 3/10=3+0.3=3.3

Donna's time: 2\ 4/5=2+0.8=2.8

Cindy's time: 4\ 3/5=4+0.6=4.6

Nicole's time: 2\ 1/10=2+0.1=2.1

As you can see, the fastest girl is Cindy and the slowest girl is Nicole.

Then, you must make the following subtraction to calculate the difference:

4.6-2.1=2.5 or 2 1/2

Help please!! Solve for y.
Nimfa-mama [501]

Answer:

y = 3\sqrt{7}

Step-by-step explanation:

The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is

\frac{y}{9} = \frac{7}{y} ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = \sqrt{63} = 3\sqrt{7}
