The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 500 people. By selling tickets, the members would like to raise
$2,550 every night to cover all expenses. Let d represent the number of adult tickets sold at $7.50.
Let s represent the number of student tickets sold at $4.50 each. If all 500 seats are filled for a
performance, how many of each type of ticket must have been sold for the members to raise
exactly $2,550? At one performance there were two times as many student tickets sold as adult
tickets. If there were 300 tickets sold at that performance, how much below the goal of $2,550 did

1.true 2.false? ? i think. .

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
