Answer:
p = (7r+16) / (4-q)
Step-by-step explanation:
4p - 7r = pq + 16
Add 7r to both sides.
4p = pq + 16 + 7r
Subtract pq from both sides.
4p - pq = 7r + 16
Factor out p from the left side.
p(4 - q) = 7r + 16
Divide both sides by (4 - q).
p = (7r + 16)/(4 - q)
The 7r and the 16 could be in either order, like 7r+16 or 16+7r. You could show that the answer is a fraction with 7r+16 on top and 4-q on the bottom. If you are writing or on the computer selecting a fraction that is stacked you don't need need the parenthesis.
we have that
y = 3x - 2
10(x+3/5)=2y------> the second equation----->divide by 2 both sides
5(x+3/5)=y-----> y=5x+3
y=5x+3------> second equation written in slope-intercept form
so
case A) y=5x+3/10-----> is not equal to y=5x+3
case B) y=5x+3--->is equal to y=5x+3---------> is the answer
case C) y=1/5x+3/25-------> is not equal to y=5x+3
case D) y=1/2x+6-----> is not equal to y=5x+3
therefore
the answer is the option
B) y=5x+3

Step-by-step explanation:
2.9(105)(7.2)(102)
5(10−8)
=
(2.9)(100000)(7.2)(102)
5(10−8)
=
(290000)(7.2)(102)
5(10−8)
=
2088000(102)
5(10−8)
=
(2088000)(100)
5(10−8)
=
208800000
5(10−8)

Answer:
25% probability that all three residents will choose the same plumbe
Step-by-step explanation:
For each resident, there are only two possible outcomes. Either they choose the first plumbe, or they choose the second. The plumbers are chosen independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Each resident randomly chooses one of the two plumbers.
This means that 
Three residents:
This means that 
What is the probability that all three residents will choose the same plumb
This is P(X = 0)(all choose the second pumble) or P(X = 3)(all choose the first pumble). So
25% probability that all three residents will choose the same plumbe
Answer:
FJH is an obtuse angle, so it is automatically larger than 90. Answer is D.
