 [tex] \pi [/tex] is an irrational number i.e. it cannot be written in the form of [tex] \frac{p}{q} [/tex] where p and q are integers and q is never equal to 0.

By multiples of [tex] \pi [/tex], we can write like:

Solve 14n+q=rt-4n for n

Answers

Hey there!

In order to solve this, all you need to do is cancel out terms until you have n on one side of the equal sign and everything else on the other side. 

14n + q = rt – 4n (add 4n to both sides to combine 4n and 14n)
18n + q = rt (subtract q from both sides)
18n = rt – q (divide both sides by 18)
n = (rt – q) ÷ 18

Hope this helped you out! :-)

The solution for n is [tex]\( n = \frac{{q - rt}}{{10}} \)[/tex].

To solve for n in the equation -14n + q = rt - 4n, we need to isolate n on one side of the equation.

First, let's gather all terms involving n on one side. Adding 4n to both sides of the equation, we get:

-14n + 4n + q = rt

Simplifying the left side, we have:

-14 + 4)n + q = rt

-10n + q = rt

Next, let's isolate n by moving the term q to the other side. Subtracting q from both sides, we have:

-10n = rt - q

Finally, to solve for n, divide both sides by -10:

[tex]\[ n = \frac{{rt - q}}{{-10}} \][/tex]

So, the solution for n is [tex]n = \frac{{q - rt}}{{10}} \)[/tex].

Final answer:

The solution to the equation -7=-1+ x/3 is obtained by adding 1 to both sides, then multiplying both sides by 3 to solve for x. This yields x = -18.

Explanation:

To solve the equation -7=-1+ x/3, we can first isolate the x term using the addition and multiplication properties of equality.

First, add 1 to both sides to cancel out -1 from the right side of the equation. This gives us -6= x/3. Then, multiply both sides by 3 to solve for x. This gives us -18=x.

Hence, the solution to the equation -7=-1+ x/3 is x=-18.

Why is it important to have complex carbohydrates before a big race?

(Again, not math. I know, its to get the answer faster..)

Answers

Complex Carbs are very useful because they are healthy and do not interfere with a race. They turn those into glucose and helps the energy be saved longer. 
Complex Carbohydrates are made up of sugar molecules strung together in long chains. Both simple and complex carbs can be turned into Glucose which is used as short term energy. This short term energy is great for short races, for marathons I suggest more lipids as well. The act of eating a lot of carbs the night before a race is called "Carb Loading"

what is the answer to 2(0.5c−1.5)−6=−2 please show work!!!!

Answers

ANSWER: c = 7

WORK:
2(0.5c - 1.5) - 6 = -2
c - 3 - 6 = -2
c - 9 = -2
c - 9+9 = -2+9
c = 7
2(0.5c - 1.5) = -2 + 6

2(0.5c - 1.5) = 4

0.5c - 1.5 = 4/2

0.5c - 1.5 = 2

0.5c = 2 + 1.5

0.5c = 3.5

c = 3.5/0.5

Frank is building a table. He needs 4 pieces of wood for the table legs. Each piece of wood needs to be 7/8 of a foot long. What is the total amount of wood he needs for the legs?
A. 3 1/2 feet
B. 3 2/5 feet
C. 4 4/7 feet
D. 4 7/8 feet

Answers

Final answer:

The correct option is (A) 3 1/2 feet. To find the total amount of wood Frank needs for the table legs, multiply the length of one leg (7/8 foot) by 4, the number of legs, resulting in 3 1/2 feet of wood in total.

Explanation:

Frank needs four pieces of wood, each 7/8 of a foot long for the table legs. To find the total amount of wood required, we multiply the length of one piece by the number of pieces:

Multiply the length of one leg, 7/8 foot, by the number of legs, which is 4.
(7/8) foot x 4 = (7/8) x 4/1 = 28/8 = 3.5 feet

Therefore, Frank needs 3 1/2 feet of wood in total for the table legs.

A relay race is 1/10 kilometer long. Four athletes will run an equal distance to complete the relay. How far does each athlete run ?

Answers

25 metres. Because 1/10th of a kilometre is a 100 metres. And four athletes divided by 100 metres is 25 metres.

Answer:

25 meters.

Step-by-step explanation:

Let us suppose each athlete run x km.

Hence, four athlete will run 4x km.

Now, the distance of the relay race is 1/10 km

Thus, we have

[tex]4x=\frac{1}{10}[/tex]

Divide both sides by 4

[tex]x=\frac{1}{40}km[/tex]

Now, 1 km = 1000 meters. Thus, we have

[tex]x=\frac{1}{40}\times1000\\\\x=25[/tex]

Thus, each athlete run 25 meters.
