Answer:
x = 6
Step-by-step explanation:
<em>Let's solve y for x + 2y = 8.</em>
x + 2y = 8
2y = -x + 8
y = 
x + 4.
<em>Let's solve y for x - y = 5.</em>
x - y = 5
y = x - 5
<em>Since both equations have been solved for y, we can combine them together into one!</em>
x - 5 = x + 4
x 
x = 4 + 5
1.5x = 9
x = 6

Answer:
A. 50 B. 27.5
Step-by-step explanation:
Answer:
.Lower quartile = 3.5
Step-by-step explanation:
Rearranging the data from lowest to highest.
2, 3, 4, 5, 6, 7, 8, 9 , 10, 15
First finding the median to make it easier to find the lower quartile.
median : 6 and 7 but right now they're irrelevant so we don't honestly need to work that out.
The lower quartile would be 3 and 4
3+4= 7 divide by 2 = 3.5 is your lower quartile
---- x ----
| | 0.25x
---- x ----
x + x + 0.25x + 0.25x = 35
2.5x = 35
x = 35/2.5
x = 14
width is 14
length is 1/4 this.
length = 7/2
