Round 19,944,074 to the nearest ten-million.

Answer and Step-by-step explanation:

(This paragraph is important:) When rounding, you should always look at the placement to the right of the number or placement that you are trying to solve. Also when rounding, any numbers from 1 - 4, do not get to be rounded up. Any numbers 5 - 9 get to be rounded up to the next number.

So in this case, we look at the 944. This number is on the scale of 5 - 9, so the placement ahead of it is rounded up. The ten millions placement is the 19 in this problem.

So, the answer to this problem is 20,000,000.

That is 19,944,074 rounded to the nearest ten million.

I hope this helps.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
