Answer:
C
Step-by-step explanation:
Paul can drive a distance of 3,375 miles in 15 days.
A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other. Proportions are represented by the symbols "::" or "=".
We have been given that Paul drives his delivery van 675 miles in 3 days.
Let he can drive a distance of x miles in 15 days.
According to the given question, we can write a proportion as
675 miles : 3 days = x miles : 15 days
⇒ 675 / 3 = x / 3
⇒ 225 = x / 3
Apply the cross-multiplication operation,
⇒ x = 225 × 15
⇒ x = 3,375
Therefore, Paul can drive a distance of 3,375 miles in 15 days.

Answer:
The entire class is done in 80 minutes
Step-by-step explanation:
20 % = 20/100 = 1/5
1/5 of the class in 16 minutes
Multiply each by 5
1/5 *5 of the class in 16*5 minutes
1 of the class in 80 minutes
The entire class is done in 80 minutes
In an arithmetic sequence, consecutive terms are separated by a common difference and are given recursively by
So we can write in terms of by substituting recursively:
and so on up to
(notice how in , it's always true that and add up to 51)
We're given that and , so we can solve for :
We can use the same strategy to find the first term in the sequence:
and so on up to
In general, the sequence has a pattern of
and so on up to
So this sequence is given by the rule

All fractions are rational.
Answer: yes choice B
Step-by-step explanation:
g(x) has -5 slope
y - g(-1) = -5(x +1)
y -5 = -5x -5
y = -5x
f(x) = xx/2 +2
Xx/2 +2= -5x
Xx/2 +5x +2 = 0
Xx + 10x +4 =0
Solutions: -5 + root(100 -16)/2
And -5 - root(84)/2
Both intersection look like in negative x values
