The +2 is a reminder to add when he multiply 4*1 (4*1=4+2=6)
4*2=8
4*5=20 (so he writes the 0 with a remainder of 2)
4*1=4+2=6
so,
152x4= 608
Answer:
x=2, y=2
Step-by-step explanation:
3x + y = 8
2x + 4y = 12
Multiply the first equation by -4
-12x -4y = -32
Then add to the second equation
-12x -4y = -32
2x + 4y = 12
------------------------
-10x + 0y = -20
-10x = -20
Divide by -10
-10x/-10 = -20/-10
x =2
Now find y
3x+y = 8
3(2)+y = 8
6+y = 8
y = 8-6
y =2
The nearest whole number rounds to 6
The nearest tenth rounds to 5.70
The nearest hundredth rounds to 5.70
Answer:
Option 2
Step-by-step explanation:
Because it shows that it is going up in a half not a whole.
The mean of a sequence of numbers is the average.
The true statement is: 
The given parameters are:


The mean of a dataset is calculated as:

So, we have:

Multiply both sides by m

When the sequence is split into two, we have:


Where:

So, we have:

Hence, the true statement is:
