Answer:

inequality 3n+5>9+n, subtract 5 from both sides to get 3n>4+n, now subtract n from both sides to get 2n>4 and divide both sides by 2 to get n>2 :)

Explain how can 9×1/4=2 1/2

Art [367]

It can't. 9 x 1/4 = 2 and 1/4. The equation in the question is a false statement.

At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F. Which statement describes the temperature?

Answer:

At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0

Step-by-step explanation:

At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F.

We can say that −3.6 lie on the LHS of a number line while 43.7 lie on RHS of the number line and 0 at the mid.

43.7°F is above 0 and 3.6°F is below 0.

At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0 . Hence, the correct option is (d).

A line contains the points (-1, 6), (6, k) and (20, 3). What is the value of k?

AURORKA [14]

Consider, pls, this option:
1. if a required line has a form y=ax+b, then points A(-1;6); B(6;k) and C(20;3) belong to it.
2. According to the item 1 it is possible to make up the system of equations for A and C:
$\left \{ {{-a+b=6} \atop {20a+b=3}} \right \ \left \{ {{a=- \frac{1}{7} } \atop {b= \frac{41}{7} }} \right.$
Knowing, that a=-1/7 and b=41/7, it is possible to write the equation of required line:
$y=- \frac{1}{7}x+ \frac{41}{7}$
3. Using coordinates of point B:
$k=- \frac{6}{7}+ \frac{41}{7} =5 \ where \ k=y$

Answer: 5.

Answer:

Plan C=12 weeks for 30 miles walked.

Step-by-step explanation:

This is a constant rate of change...the number of miles each week increased by 10 each time; the number of weeks was divided each time by 2. To find Plan C, divide 24/2, which is 12.

Hope this helps! Have a great day C:
