Answer:
x + y = 220
25 x + 15 y = 4650
The above system can be used to find the number of adult and student tickets sold.
Step-by-step explanation:
Let us assume the number of Adult's ticket sold = x
And The number of student's tickets sold = y
Now, total number of tickets sold = 220
⇒ x + y = 220
Cost of 1 adult Ticket = $ 25
⇒ Cost of x adult tickets = x ( $25) = 25 x
Cost of 1 student Ticket = $ 15
⇒ Cost of y student tickets = y ( $15) = 15 x
Also, the total amount made from selling all tickets = $4650
⇒ 25 x + 15 y = $4650
Here, the given system of equations are:
x + y = 220
and 25 x + 15 y = 4650
The above system can be used to find the number of adult and student tickets sold.
Answer: okay wow I dunno the answer sorry bud
Step-by-step explanation:
Answer:
x = 40.
Step-by-step explanation:
The corresponding sides are in the same proportion so:
45/ 27 = 30/18 = x/24
Consider the last 2 fractions:
30/18 = x/24
5/3 = x/24 Cross multiply:
3x = 5 * 24
x = 120 / 3
x = 40.
One pound is 16 ounces so 28 pounds is 28x16 which is 448. 448 divided by 8 ounces per serving is 56 ounces per bag
Answers
1) 4
2) 0, 2, -10
3) 0, 5, -2
Step-by-step explanation:
1) x³ - 64 = 0
x³ = 64
x = 4
2) x³(x² + 8x - 20) = 0
x³(x² + 10x - 2x - 20) = 0
x³(x(x + 10) - 2(x + 10)) = 0
x³(x + 10)(x - 2) = 0
x = 0, 2, -10
3) x³ - 3x² - 10x = 0
x(x² - 3x - 10) = 0
x(x² - 5x + 2x - 10) = 0
x(x(x - 5) + 2(x - 5)) = 0
x(x - 5)(x + 2) = 0
x = 0, 5, -2
