6.23+ -12.49 -2.6= 6.23+ -12.49+ -2.6
-6.26+-2.6= -8.86
Answer:
81000 people went to Bonnaroo.
192000 people went to Lollapalooza.
Step-by-step explanation:
Given:
Total number of people attending festivals, 
Number of people attending Lollapalooza is 30,000 more than twice the people attending Bonnaroo.
Unknown:
Number of people attending Lollapalooza and Bonnaroo.
Let the number of people attending Bonnaroo be
.
Therefore, the number of people attending Lollapalooza is equal to 
Evaluate:
Sum of people attending Bonnaroo and Lollapalooza is equal to the total number of people attending the festivals. So,

Substitute and Solve:
Now, we have,
.
Substitute 81000 for
and solve for the number of people attending both the festivals. This gives,
Number of people attending Bonnaroo = 
Number of people attending Lollapalooza = 
Therefore, 81000 people went to Bonnaroo and 192000 people went to Lollapalooza.
Given Mr. Engle’s total income, I = $52,000 and total expenses, E = $53,800, solving for average difference between income and expenses per month:
(I-E)/12 = ($52,000 - $53,800)/12
(I-E)/12 = - $1,800/12
(I-E)/12 = -$150
This means that Mr. Engle’s expenses exceed his income by an average of $150 each month in the said year.
Answer:
The mean = 14.3. median = 15.5 and the range = 10.
Step-by-step explanation:
10, 16, 19, 13, 12, 17, 16, 15, 9, 16
The mean = sum of the 10 numbers / 10 = 143/10 = 14.3.
Find the median by arranging in ascending order:
9, 10, 12, 13, 15, 16, 16, 16, 17, 19
The median is the mean of the 2 middle numbers = (15 + 16)/2
= 15.5.
The range = highest - lowest number = 19 - 9 = 10.
The second equation has 4x in it t. So to eliminate X, you need to multiply y = x-2 by -4, so the x would become -4x.
