45/ 360 = 6/x
45x = 2160
x - 2160/45 = 48 people

2)
n = (n - 1) - 5

3)
7x - 11 = 19 - 3x
add 3x to both sides:
10x - 11 = 19
add 11 to both sides:
10x = 30
divide both sides by 10:
x = 30/10 = 3

4)
4(8)(11) - 64 = 288

5)
(5, 0)

6)
-4x -3 + 2x - 6 = -2x - 9

7)
1.8(-20) + 32 = -4F

8)
Exterior angle add to 360
360/6 = 60 degrees

10)
2x/9 = 12
2x = 108
x = 108/2 = 54

11)
x = 0

12)
8 + 3 + 1 = 12
240/12 = 20
8(20) = 160
3(20) = 60
1(20) = 20

160 pounds, 60 pounds, 20 pounds

Please help me I need help please?

A linear function is a function that creates a straight line when graphed. The difference between this graph and others is that this function is constant instead of curved. I’d like to see an example of this in the real world as a relationship between profit and merchandise.A quadratic function is a function that has multiple variables allowing the graph to curve. The difference between this function and the others is that this function is squared allowing for a greater curve that looks like a U. I’d like to see a example of this in the real world as missiles being launched since the curve is similar.A exponential function is a function in which the function grows at a fast rate. The difference between this function and the others is that this function curves in a constant rate then the x increases continuously. I’d like to see an example of this in the real world as the interest in a bank since it increases per month.

Surface area of a right cone. <br>Solve for P S=2b+ph
Leya [2.2K]
S = 2b + ph

Lets subtract both sides by 2b

s - 2b = ph

Now, divide both sides by h

(s-2b)/h = p

Hope this helps!

In a new york state daily lottery game, a sequence of four digits (not necessarily different) in the range 0-9 are selected at r
Anna [14]
<span>There are 10,000 (10*10*10*10) possible sequences. There are 4C3 ways, 4, of having exactly three digits be the same value. The differing digit can be any of the four positions. There are 10P2 ways, 90 (10*9), to choose the digits of the sequence since we have 10 choices for the digit to be repeated, then 9 more options or the differing digit. The product of the combination arrangements and permutation selection, 4*90, shows there are 360 sequences with three of the same digit. Thus the probability is 360/10,000 or 0.036 or 3.6%.</span>
