The sixth number should be 16 in order for the mean to be 12
X = 3
y = -1
get the x or y by itself first (second eq. is easier)
So, x + 2y = 1
-2y -2y
Now we get:
x = -2y +1 Plug it into the other equation.
2x + 3y = 3
2(-2y +1) + 3y = 3
-4y + 2 + 3y = 3
-1y +2 = 3
+1y -3 -3 +1 y
y = -1 (plug into either eq to get x)
<span>x + 2y = 1
</span>x+2(-1) = 1
x-2=1
+2 +2
x = 3
192
Next time try to add more points bc i worked so hard to answer this
Answer:
n=-18
Step-by-step explanation:
subtract 8 from both sides.
then you do -10 subtracted by 8 and thats -18.
Answer:
Step-by-step explanation:
diameter = 4.275"
r = 4.275 ÷ 2 = 2.1375"
Area of circle = πr²
= 3.14 * 2.1375 * 2.1375
= 14.3463
≈ 14.3 in²
