The answer is: 12.8 F
The solution: -10.6+14.2+11-1.8
Answer:
C and B
Step-by-step explanation:
(6)
×
← cancel 3x - 7y on numerator and denominator
=
×
=
=
→ C
(7)
÷ 
Factorise the denominators of both fractions
x² - 9 = x² - 3² = (x - 3)(x + 3) ← difference of squares
4x - 12 ← factor out 4 from each term
= 4(x - 3)
Then rewrite as
÷
← cancel 8 and 4 by 4
=
÷ 
• leave first fraction, change ÷ to × , turn second fraction ' upside down'
=
×
← cancel x - 3 on numerator and denominator
=
×
← cancel 2 and 6 on numerator and denominator
=
→ B
Let's say "the second number" is y so y= 7(x) And x+y= 32
you would plug in y=7x into x+y=32 and that would look like this....x+7x=32
then you would add the x's and that would look like.... 8x=32 then you would divide 32/8 and get x =4 to find y, you just plug in x=4 into x+y=32
but I did most of the work so you can find y ;)
its not that hard... im sure you can do that;))))
Answer:
what is the question
Step-by-step explanation:
To calculate the mean absolute deviation, you first must find the mean of the data and then find the difference between each piece of data and the mean.
Please see the attached picture for the work.
The mean absolute deviation is approximately 1.48.
This means that the numbers of candies in the 10 bags are all very close to one another. There is not much variation.
