Answer:
C
Step-by-step explanation:
You are given two matrices A and B.
1. Find 2A by multiplying each element of A by 2:
2. Find 4B by multiplying each element of B by 4:
3. Subtract two matrices 2A and 4B (from each element of matrix 2A subtract corresponding element of matrix 4B)
Answer:
x=7
Step-by-step explanation:
6x +2y=48
Let y=3
6x+2(3) = 48
6x+6 = 48
Subtract 6 from each side
6x+6-6=48-6
6x= 42
Divide by 6
6x/6 = 42/6
x = 7

Answer:
x = 5
y = 4
Step-by-step explanation:
1. 2x + 2y = 18
2. x + 3y = 17
Multiply the first equation by 1 and the second equation by 2 to eliminate x
We have
2x + 2y = 18
2x + 6y = 34
Subtract equation 2 from equation 1
-4y = -16
Divide both sides by -4 to isolate y
-4y/-4 = -16/-4
y = 4
Now substitute 4 for y in either equation to get x. Using equation 2 we have
x + 3y = 17
x + 3 x 4 = 17
x + 12 = 17
Subtract 12 from both sides
x + 12 - 12 = 17 - 12
x = 5
x = 5 and
y = 4

If we presume you're interested in creating pie chart of medal distribution, the arc measure is proportional to the medal count. The sum of arc measures is 360°; the sum of medal counts is 35+39+29 = 103. Then the arc measures are
.. arc ADB = (35/103)*360° = 122.3°
.. arc BDC = (39/103)*360° = 136.3°
.. arc CDA = (29/103)*360° = 101.4°
