A charity fair raised $6,000 by selling 500 lottery tickets. There were two types of lottery tickets: A ticket costs $10 each an
soldier1979 [14.2K]
We have 2 types of tickets, A tickets and B tickets.  The total number of tickets sold was 500, so an equation for this NUMBER of tickets is A + B = 500.  The MONEY equation is something different.  A tickets cost 10, so they are represented by 10A; B tickets cost 60, so they are represented by 60B.  The total dollar sales for A and B are 6000.  Our money equation for the sales is 10A + 60B = 6000.  Solve the first equation for A:  A = 500 - B.  Sub that value for A into the second equation to solve for B:  10(500-B) + 60B = 6000.  Distribute through the parenthesis to get 5000 - 10B + 60B = 6000.  Combine like terms to get 50B = 1000.  B = 20.  There were 20 type B tickets sold.  A = 500 - B, so A = 500 - 20 and A = 480.  There were 480 type A tickets sold.

irga5000 [103]

Answer:

90

12

0.0154

Step-by-step explanation:

a) #Possible experimental run=#Temp x #pres x #cat=3x5x6=90

b) #Possible experimental run=(Temp. lowest) x 2.pres x #cat=1x2x6=12

c) C="different catalyst is used on each run"

In the first, I can choice 6 of 6 catalysts, in the second 5 of 6,...

then: P(C) = 6/6 x 5/6 x 4/6 x 3/6 x 2/6 x 1/6 = 5/324 = 0.0154

What is the value of x? enter your answer in the box
Bas_tet [7]
They are vertical angles, and so they will equal the same <em>degrees</em>

set the two equal to another

2x + 2 = 3x - 52

Move all numbers with variables to one side, and all constant to the other

2x (-3x) + 2 (-2) = 3x (-3x) - 52 (-2)

2x - 3x = - 52 - 2

-x = -54

isolate the x, divide -1 from both sides

-x/-1 = -54/-1

x = -54/-1

x = 54


x = 54°

hope this helps
