We can set up an equation to solve this problem. I am setting the number of marbles in a red jar to R.
R + R + R - 16 = 41
We solve this by adding 16 to both sides and combining all of the R terms.. This gives us:
3R = 57
We can finish this problem by dividing both sides by 3.
R = 19. So, there are 19 marbles in a red jar.
We can easily figure out how many marbles are in a blue jar by subtracting the total amount of marbles in 2 red jars from the total amount of marbles. I am setting the amount of marbles in a blue jar to B.
41 - 19*2 = B
B = 3
So, there are 3 marbles in a blue jar and 19 marbles in a red jar.
Just matter of combining like terms
6x - 7 - 11x + x =
(6x + x - 11x) - 7 =
(7x - 11x) - 7 =
- 4x - 7 <===
4a-3
because 4(a-3) what’s in () can’t be done so you go to the next step in pemdas and multiply and then you write it out and your done

Step-by-step explanation:
X(mean) = (600470170430300 + 23056 + 22123 + 21704 + 20365) / 5 = 120094034103510
n=5
S²(variance) = ((600470170430300-120094034103510)²+(23056-120094034103510)²+(22123-120094034103510)²*+(21704-120094034103510)²+(20365-120094034103510)²/(5-1)
S² = 72112885110079700000000000000.00
