-8x + y = 6
in the first equation, isolate y and then it becomes...
y = 6 + 8x
use this to replace the y in the second equation.
7x - 1y = -4
let y = 6 + 8x
7x - (6 + 8x) = -4
7x - 6 - 8x = -4
-x - 6 = -4
x + 6 = 4
x = 4 - 6
x = -2
now use this x = -2 into the equation with y.
y = 6 + 8x
y = 6 + 8(-2)
y = 6 -16
y = -10
Therefore, x = -2 and y = -10

6+5 = 11
99/11 = 9
9x6 = 54
so 54 cupcakes
Hope this helps, and May the Force Be With You!

Answer:
Step-by-step explanation:
Given the data:
34, 18, 29, 60, 44, 51, 65, 68.
Ordered data :
18, 29, 34, 44, 51, 60, 65, 68
The five number summary :
Sample size = 8
Minimum = 18
Lower quartile (Q1) = 1/4 (n+1) = 9/4 = 2.25
(2nd + 3rd term) / 2
= (29 + 34) / 2 = 31.5
Using calculator :
Median (Q2) = 47.5
Upper quartile (Q3) = 62.5
Maximum = 68
2.) With the information above, the museum curator could use this to guide their stock preference by stocking up gifts suitable for adults and youths, stockingbup with children's gift may be a bad options as visitors are atleast 18 years of age.
