Fill in each slot in the square with variables <em>a</em>, <em>b</em>, <em>c</em>, <em>d</em>, and <em>e</em>, in order from left-to-right, top-to-bottom. In a magic square, the sums across rows, columns, and diagonals all add up to the same number called the <em>magic sum</em>.
The magic sum is -3.9, since "diagonal 2" (bottom left to top right) has all the information we need:
3 + (-1.3) + (-5.6) = -3.9
Use this to find the remaining elements
<em>a</em> + <em>b</em> + (-5.6) = -3.9
<em>c</em> + (-1.3) + <em>d</em> = -3.9
3 + <em>e</em> + 0.02 = -3.9
<em>a</em> + <em>c</em> + 3 = -3.9
<em>b</em> + (-1.3) + <em>e</em> = -3.9
(-5.6) + <em>d</em> + 0.02 = -3.9
- diagonal 1 (top left to bottom right):
<em>a</em> + (-1.3) + 0.02 = -3.9
You will find
<em>a</em> = -2.62
<em>b</em> = 4.32
<em>c</em> = -4.28
<em>d</em> = 1.68
<em>e</em> = -6.92
When you have 8(s-3) you are find a product of 8 times whatever s-3 is however s-3 you are find the difference between whatever s is and 3.
Answer:
(6,-2.5)
Step-by-step explanation:
The formula for the midpoint between two points is:
Now we substitute
We have than (9, -1) is 
and (3, - 4) is 
So:
So, we have:
<h2>(6,-2.5)</h2><h2 />
I can do a graphic explanation if you want.
Answer:
-17/2 =x
Step-by-step explanation:
9–5(x+4)=3(2–x)
Distribute
9 - 5x - 20 = 6 -3x
Combine like terms
-5x-11 = 6-3x
Add 5x to each side
-5x-11 +5x = 6-3x+5x
-11 = 6+2x
Subtract 6 from each side
-11-6 = 6+2x-6
-17 = 2x
Divide by 2
-17/2 = 2x/2
-17/2 =x
Answer:
Your answer is C. 1/2 (16*6) = 48 square feet
Step-by-step explanation:
The formula to find the area of a triangle is A = b*h/2 (base times height divided by half)
First you need to multiply the base (6) by the height (16).
6*16 is 96.
Now you divide 96 by 2 or cut it in half.
96/2 (or cut in half) is 48.
Therefore your answer is C
