Answer:
97%
Step-by-step explanation:
for such a question we can use the percentage numbers like real unit numbers, as we need to analyze just the percentage numbers and align them with another percentage number with the result of another percentage number.
so, we just use the percentage numbers and deal with mean values and such like with real unit numbers.
therefore we need to find x
(79 + 92 + 71 + 86 + x) / 5 = 85
as the sum of all numbers divided by the number of measurements is the mean value.
and so,
79 + 92 + 71 + 86 + x = 425
328 + x = 425
x = 97
so, the next site must be 97%, so that the average for the 5 surveys will be exactly 85%
Antonio has 24 coins in his pocket this is how I found the answer
(5/8)x=15
x=15/ (5/8)
x=15*(8/5)
x=120/5
x=24
I really hope this helps
Answer:
joan is 15
Step-by-step explanation:
27+3=30

Here is the solution:
-3x-42<span> > 3
Add the numbers
-3x > 45
Divide both sides of the inequation by -3 and flip the inequality sign.
x < -15
So the answer is: </span>x < -15
