The system of equations would be:
64x+132y = 1040
x = 2y
We multiply the number of adult tickets, 64, by the cost of the adult tickets, x. We multiply the number of student tickets, 132, by the cost of the student tickets, y. Together these add up to $1040.
We know that the cost of an adult ticket is twice as much as a student ticket, so x = 2y.
1/2 * n = 2n + 14
Multiply everything by 2 to get rid of the fraction
n = 4n + 28
n - 4n = 28
-3n = 28
n = -9.333333
n = -28/3
Answer:
23 degrees
Step-by-step explanation:
6x + 42 = 180
x = 23
First, you round your numbers:
162% to 160
and
79 to 80
I would divide 160 (%) by 80 which, obviously, is 2
My best estimate would be 2
Hope this helps!

5 is the <em>smallest</em> number by which 35280 must be multiplied so that the product will be a <em>perfect</em> square.
<h3>What number must be an integer multiplied by to find a perfect square? </h3>
A number is a <em>perfect</em> square if the following property is satisfied:
a = b², where is a <em>natural</em> number.
Please notice that b can be either a <em>prime</em> number or a product of <em>prime</em> numbers.
Initially, we proceed to factorize 35280 by factorial decomposition, that is, as a product of <em>prime</em> numbers:
35280 = 2⁴ × 3² × 5 × 7²
35280 = (2²)² × 3² × 5 × 7²
35280 = 4² × 3² × 5 × 7²
Then, we must add a 5 to find a product that is a perfect square:
4² × 3² × 5² × 7² = 176400
5 is the <em>smallest</em> number by which 35280 must be multiplied so that the product will be a <em>perfect</em> square.
