7 9/12 = 7.75
2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8
2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.

Answer:
B. 10
Step-by-step explanation:
To find the answer we would plug each given number into x to see if it makes the equation true
<em>A. 2(5) = 20 </em>
<em> 10 </em>
<em> 20</em>
<em>B. 2(10) = 20</em>
<em> 20 = 20</em>
<em>C. 2(20) = 20</em>
<em> 40 </em><em>20</em>
As you can see, the only answer that makes the equation 2x=20 true, is answer B
Answer:
Without a table, we can't really complete one.
This can be easier though if you realise that:
y = x^2 - x
is identical to:
y = x(x - 1)
In other words, the table values are just 1 × 0, 2 × 1, 3 × 2, 4 × 3, etc., giving you the series (starting with x = 1)
0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, ...
This If you plot this on a graph, it gives you a parabola that opens upward. It's vertex is at (0.5, -0.25)
Answer:
y - 4 = 2(x + 6)
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h):
y - 4 = 2(x + 6)
