Mean is when you add up all the numbers, then divide by how many numbers there are
<span>39 + 43 + 46 + 86 + 22 + 39 + 75 = 340
340 </span>÷ 7 (because there are 7 numbers) = 48.57
Answer:
10x + 5y = 11
Step-by-step explanation:
I usually find it in slope intercept then convert, it's easier for me.
First you find slope using delta y over delta x giving you -2/5.
so you have y=-2/5x + b
To find b plug in a point and solve down
1 = -2/5(3) +b
1+6/5 = b
b = 11/5
y=-2/5x + 11/5
Then you convert it to Ax+by=C form,
multiply by 5
5y = -10x + 11
move x
10x +5y = 11
Answer:
x ≤ 30
Step-by-step explanation:
'at most' means the same as 'less than or equal to'.
The sign 'for less than or equal' to is ≤.
So it's simply x ≤ 30.
