Answer:
No solution or x ∈ ∅
Step-by-step explanation:
We have given the equation ⇒ x+12 = (x+14) -3
if we solve this equation ⇒ x+12 = x+14-3
⇒x+12= x+11
⇒12 ≠ 11
which state that x ∈ ∅
i.e. there is no value of x which make the equation true
therefore, No solution

Step-by-step explanation:
We can make prediction about a population based on the outcome of a sample statistic.
From a random sample of voters, n ; the number who voted Smith = x
(p = x / n) gives the proportion of votes Smith will get according to the sample :
For instance :
n = 100 ; x = 10
p = 10 / 100 = 0.1
The predicted Number of votes Smith will Get if there are 10000 voters :
p * 10000
0.1 * 10000
= 1000 votes
Answer:
Alvin traveled 150 miles downstream and 150 miles upstream, for a total distance on the river of 300 miles.
Step-by-step explanation:
Let d represent the distance Alvin traveled in one direction on the river. Then going downstream that distance took ...
... time = distance/speed
... time downstream = d/25
and the time going upstream that same distance to his point of origin took ...
... time upstream = d/15
The total of these times is 16 hours, so we have ...
... 16 = d/25 + d/15
Multiplying by 75 gives ...
... 1200 = 3d +5d = 8d
... 1200/8 = d = 150
Alving spent 6 hours going 150 miles downstream and 10 hours going 150 miles upstream. His total river distance was 300 miles. (We cannot tell which of these numbers will be considered to be the answer to the question.)
