6+5x=?
x = is the missing number so when you find x you multiply 5 and x and that will give you your answer
ANSWER MIGHT BE
11x
Given:
Sum of interior angle
To find:
Number of sides of a polygon
Solution:
Using sum of interior angles formula:

where "S" is the sum of interior angels and "n" is the number of sides of a polygon.
Divide by 180° on both sides.

Cancel common factor 180°.

Add 2 on both sides.


Switch the sides.

Therefore number of sides of a polygon is
.
Answer:

Step-by-step explanation:

Let's solve one of them for x.

Add 4

Divide by 3.

Now, plug the value of y in the formula, or you can plug the value of x in the other equation. I'll take this one.




Multiply by 3 to get rid of the denominator.

add x

Combine like terms;

Divide by 4.

Simplify.

Now that you found the value of x, replace it in any of the equations to find y.


Proof:




Answer and Step-by-step explanation:
We know that t is in minutes, and 1 hours is equal to 60 minutes, so we plug in 60 for t.
C = 0.25(60) + 3.50
C = 15 + 3.50
C = 18.50

There are 2001 items in that set.
So n(A) = 2001
We can individually count them all out, which is very slow and tedious, or we can use the formula
n-m+1
where,
m = starting value
n = ending value
In this case,
m = 0
n = 2000
So,
n-m+1 = 2000-0+1 = 2001
This formula only works if we increase the number by 1 each time (eg: 6, 7, 8, etc)
