Answer:
37/6
Step-by-step explanation:
Simplify the following:
(12 + 1/3)/2
Put 12 + 1/3 over the common denominator 3. 12 + 1/3 = (3×12)/3 + 1/3:
((3×12)/3 + 1/3)/2
3×12 = 36:
(36/3 + 1/3)/2
36/3 + 1/3 = (36 + 1)/3:
((36 + 1)/3)/2
36 + 1 = 37:
(37/3)/2
37/3×1/2 = 37/(3×2):
37/(3×2)
3×2 = 6:
Answer: 37/6
Let's find the mean of all the values first.
6.3+6.4+6.5+6.6+6.8+6.8+7.5= 46.9
Let's divide by the number of values.
46.9÷7=
6.7
Now let's find the distance that each number is away from 6.7 and find the mean of those numbers.
0.4+0.3+0.2+0.1+0.1+0.1+0.8=
.2857
≈ 0.3
So, the absolute deviation is 0.3.
Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get
9x + 5y - 9x + 4y = -33 + 6
9y = -27
y = -3
Substituting this value of y in the first equation, we get
-9x + 4(-3) = 6
-9x - 12 = 6
9x + 12 = -6
9x = -18
x = -2
Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.
