P=A/(1+r)T
Step-by-step explanation:
1) p(1+r)=A/T
2)P=A/(1+r)T
C=(1/4)*circumference
Area=pq+3.142r^2
60*3.142=pq+3.142p^2
q=((1/4)*2p*3.142)+2*3.142
q=1.571p+6.284
188.52=1.571p^2+6.284p+3.142p^2
188.52=4.713p^2+6.284p
188520=4713p^2+6284p
26 adult tickets = $12 (cost of an adult movie ticket) • 26 = $312
There were $312 dollars worth of money sold from the adult tickets that were sold for the 10PM show.
$600 - $312 = $288
This means that there were $288 dollars worth of money sold from children’s tickets for the 10PM show.
Since each children ticket is $8, you would do
8x = $288
(X IS HOW MANY CHILDREN TICKETS THAT WERE SOLD)
Once you do that, you would simplify it by dividing 8x by 8 which would give you x by itself and do the same thing for the other side as you have to do the same for both sides of the equal sign. So, you would do $288 divided by 8 and get 36.
x = 36
To check our work, we will substitute the value of x into the equation
8(36) = $288
288 = $288
Therefore, there were 36 children tickets sold for the 10PM show.
Answer:
Answer:
Silk = x = 1.5 yards
Cotton = y = 2.75 yards
Step-by-step explanation:
x + y = 4.25
16.90x + 4y = 36.35
1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.
2.
x + y = 4.25 (1)
16.90x + 4y = 36.35 (2)
Multiply (1) by 4
4x + 4y = 17 (3)
16.90x + 4y = 36.35 (2)
Subtract (3) from (2)
16.90x - 4x = 36.35 - 17
12.90x = 19.35
Divide both sides by 12.90
x = 19.35 / 12.90
= 1.5
x = 1.5 yards
Substitute x = 1.5 yards into (1)
x + y = 4.25
1.5 + y = 4.25
y = 4.25 - 1.5
= 2.75
y = 2.75 yards
Silk = x = 1.5 yards
Cotton = y = 2.75 yards
