Photo math works, but just saying two step equations are pretty fun! The goal is to get the variable (x) by itself; alone on one side of the equal sign. I’m going to explain #1. 7x has to be by itself, so you will move the +9 over to the other side of the equal sign. When you move a number/thing over the equal sign, it turns negative (negative turns to positive, positive turns to negative). So, it will become 7x = 58 -9. You will do simple subtraction to get 7x = 49. Divide each side by 7 to get x by itself, and you have x = 7!

Sheila can ride her bicycle 6000 meters in 15 minutes. How far can she ride in 2 minutes?
iren [92.7K]
<span>Sheila can ride her bicycle 6000 meters in 15 minutes. 
Forming that into a ratio, that will be 6000 : 15

Doing the proportion for 2  minutes.
6000 : 15 = X : 2

Doing the computation.
6000 / 15 = X / 2
15X = 2 * 6000
15X = 12000
X = 800

So Sheila covered a total of 800 meters in 2 minutes.</span>

Write an equation of lines whose graph is parallel to the graph of y=3x-10
katrin [286]

A music website tracked the number of new users per day over 1 week. The number of new users for each day of the 7 days was 38,
enyata [817]
Part a)

MAD = median of absolute deviations

MAD = median of the set formed by : |each value - Median|

Then, first you have to find the median of the original set

The original set is (<span>38, 43, 45, 50, 51, 56, 67)


The median is the value of the middle (when the set is sorte). This is 50.


Now calculate the absolute deviation of each data from the median of the data.

1) |38 - 50| = 12
2) |43 - 50| = 7
3) |45 - 50| = 5
4) |50 - 50| = 0
5) |51 - 50| = 1
6) |56 - 50| = 6
7) |67 - 50| = 17

Now arrange the asolute deviations in order

(0, 1, 5, 6, 7, 12, 17)

The median is the value of the middle: 6.

Then the MAD is 6.

Part b) MAD represents the median of the of the absolute deviations from the median of the data.
