x = 48
Step-by-step explanation:
3x + 9 = 153
subtract 9 from both sides -9 -9
3x = 144
divide both sides by 3 3x/3 = 144/3
2x + (x + 9) = 153
2(48) + (48 + 9) = 153
96 + 57 = 153
153 = 153

We are given that The five-number summary for the scores of 300 nursing students are given :
Minimum = 40

Median = 82

Maximum = 100
is the first quartile and is the median of the lower half of the data set. 25% of the numbers in the data set lie below
and about 75% lie above
.
is the third quartile and is the median of the upper half of the data set. 75% of the numbers in the data set lie below
and about 25% lie above 
i) .About how many students scored 65 or better?

Since we know that 75% lie above
.
So, Number of students scored 65 or better = 
ii)About how many students scored 88 or better?

Since we know that 25% lie above
So, Number of students scored 88 or better = 
Hence 225 students scored 65 or better and 75 students scored 88 or better.
All you need to do is distribute the 8 into each of the terms in the parenthesis.
Your equation will then become
32x + 48y - 24z
