Answer:
$36 (see below)
Step-by-step explanation:
First, you have to find how much they paid for one ticket.
If they paid $12 for 3, then they paid $4 for 1.
You could've also use a ratio:
$12 $x
-------- = --------
3 1
Cross multiply:
$12 (1) = $3x
$12 = $3x
$4 = x
So $4 for 1 ticket.
To find the cost of 9 tickets, just multiply the price by the number of tickets, which is:
$4 (9) = $36
Answer: 200 hats in total
Steps:
x * .4 = 80
x = 80/.4
x = 200
Check:
200 * .4 = 80
80 = 80 ✅
Answer: y = -3
<u>Step-by-step explanation:</u>
-8x - 5y = -1
<u>+8x </u> <u>+8x </u>
-5y = 8x - 1
<u> ÷-5 </u> <u> ÷-5</u> <u>÷-5</u>
y =
y(2) =
=
=
= -3
Length of diagonal, l = √(a² + b²)
l = √(130² + 200²)
l = √(16900 + 40000)
l = √56900
l = 238.537
After rounding-off to the nearest whole number, it would be 239.
In short, Your Answer would be Option D
