Answer:
189 tickets sold on Saturday.
Step-by-step explanation:
Your ratio of 8:1 is children's tickets to adult tickets.
There are 8 times as many children tickets sold as adult tickets.
Let c = # children's tickets
Let a = # adult tickets
8a = a + 147
subtract a from both sides
7a = 147
divide on both sides by 7
a = 147/7
find number of adult tickets
a = 21 adult tickets
multiply the number of adult tickets by 8 to find children's tickets 21*8=168
168+21=189 tickets sold on Saturday.
Answer:
3
Step-by-step explanation:
A ball is 10 meters. Since 100 centimeters are in a meter, each ball has 100*10 = 1000 centimeters.
The teacher needs 70 strings each 40 centimeters. The total amount they need is 70*40 = 2800 centimeters.
Since a ball has 1000 centimeters, 2800 centimeters will need 3 balls for a total of 3000 centimeters.
Answer:
I am going to show you the first steps to complete squares for the given equation: 1) Starting equation: 3x^2 + 9x -4 = 0 2) Add 4 to both sides => 3x^2 + 9x - 4 + 4 = 4 => 3x^2 + 9x = 4 3) Extract common factor 3 in the left side => 3 (x^2 + 3x). Now, compare with a(x^2 + 3x) and you get a = 3. Answer: a = 3.
