Answer:
When you distribute something, you are dividing it into parts. In math, the distributive property helps simplify difficult problems because it breaks down expressions into the sum or difference of two numbers.
Good luck !
Firstly, you've got to expand the brackets, this becomes;
8a-4= -10a+ 50
You've then got to eliminate the -10a and you do this by adding 10a to both sides,
This then becomes 18a-4=50
You've then got to add 4, to eliminate this, which then becomes 18a=54
You've then got to divide both sides by 18, and this becomes 3.
Therefor, a=3
Hope this helps :)
Answer:
2995
Step-by-step explanation:
The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set
1127
1482
2995
3009
3250
3250
3445
3449
4000
6120
rearranging the data sets from the least to the highest
the middle number of the data sets is 3250
the middle number between the smallest number and the median of the data set is 2995
