I need help with easy math​
spin [16.1K]

Answer: x = -1 and y = 9

The two equations are:

-9x + 2y = 23

-4x -y = -3

Now find for x in the first equation...

-9x + 2y = 23

-9x = 23 - 2y

x = (23 - 2y)/-9

Now place this value of x in the second equation and find for y...

-4{(23-2y)/-9} - y = -3

-92 + 8y + 9y = -3 * -9

17y = 27 + 92

y = 119/17

y = 7

Now place the value of y in the first equation," -9x + 2y = 23 " and find x

-9x + 2*7 = 23

-9x + 14 = 23

-9x = 23-14

x = 9/-9

x = -1

There you go! Hope it helps

To show the variation in a set of data, what do you calculate?
Pavel [41]
The range is the simplest measure of variation . It is the difference between the biggest and smallest random variable.


Range= maximum value - minimum value


ex. Therefore in the range of these variables: (2,4,4,7} you would do 7 minus 2

A man drove 15/4 miles from his home to his office. He then went out for lunch to a nearby restaurant 2/3 miles from his office
Genrish500 [490]
Let's get all of the distances lined up:

\frac{15}{4} = home to office
\frac{2}{3} to a restaurant
\frac{2}{3} back to the office
2 = store
\frac{11}{6} = back home

So then we just add up all of the numbers. However we need to make sure that there is a common denominator. Let's make the common denominator 12, since that is a common factor to all of the denominators in the problem:

\frac{45}{12} = home to office
\frac{8}{12} to a restaurant
\frac{8}{12} back to the office
\frac{24}{12} = store
\frac{22}{12} = back home

Then let's add them up:

\frac{45}{12} + \frac{8}{12}+ \frac{8}{12}+ \frac{24}{12}+ \frac{22}{12}= \frac{107}{12} miles

This does not reduce to a nice number, however, we can simplify to:

8 \frac{11}{12}miles
