b = number of tickets sold before
a = number of tickets sold after
cost of a ticket = number of tickets times cost per ticket
before cost = 39.95b
after cost = 54.95a
total cost = 925000
39.95b + 54.95a = 925000
total number tickets = 20000
b + a = 20000
we have
39.95b + 54.95a = 925000
b + a = 20000
multiply second equation by -39.95 and add to first equation
39.95b + 54.95a = 925000
-39.95b-39.95a = -799000 +
0b+15a = 126000
15a = 126000
divide bot sides by 15
a = 8400
sub back
b + a = 20000
b+8400 = 20000
minus 8400 both sides
b = 11600
11,600 tickets sold before
8400 tickets sold after
Answer:
The length of the hypotenuse is
Step-by-step explanation:
we know that
In a right triangle
Applying the Pythagoras Theorem
where
c is the hypotenuse
a,b are the legs of the right triangle
substitute the values
Simplify
You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.
40 × 0.20 = 8
So now you would subtract 8 from the cost of 40.
40 - 8 = 32.
The shirt costs $32.
10minutes= 10/60 hours
= 1/6 hrs
speed = distance/ time
=3/ (1/6)
= 18 km/h
Answer:
JL = 50
Step-by-step explanation:
Since K is the midpoint of JL , then
JK = KL , substitute values
6x + 7 = 9x - 2 ( subtract 6x from both sides )
7 = 3x - 2 ( add 2 to both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Thus
JL = JK + KL
= 6x + 7 + 9x - 2
= 15x + 5
= 15(3) + 5 = 45 + 5 = 50
