The picture shows how this would look as a triangle.
In this case, we would use tan. x is the opposite side, and 80 is adjacent.
tan(85.7) = x/80
13.299.. = x/80
x = 1,064 feet

The table below shows four systems of equations:
Ede4ka [16]
To determine which system of equations would have the same solution, we evaluate each system of equations.

System 1 4x − 5y = 2, 3x − y = 8
x = 38/11
y = 26/11

<span>System 2 4x − 5y = 2, 3x − 2y = 1
x = 1/7
y = -2/7

System 3 4x − 5y = 2, 3x − 8y = 4
x = -4/17
y = -10/17

System 4 4x − 5y = 2, 10x − 9y = 4
x = 1/7
y = -2/7

</span><span>
Therefore, the correct answer is option 3. </span><span>System 2 and system 4 are equal, because the second equation in system 4 is obtained by adding the first equation in system 2 to two times the second equation in system 2.

     4x− 5y = 2 2( 3x − 2y = 1)
-----------------------    10x - 9y = 4</span>

Sever21 [200]

Answer:

$47

Step-by-step explanation:

Given: Store manager have predicted that 150 blanket can be sold at $32 each.

Also he has predicted sales of 2 blanket will decrease with $1 increase in price.

Now, finding price at which 120 blanket can be sold.

As we know cost of 150 blanket is $32 and we are finding for 120 blanket, which mean we have to increase price to decrease sales.

∴ 150-120 = 30\ blankets

Using unitary method to find correct price.

For 2 decrease in sales = $1 increase in price                

∴ 30 decrease in sales of blanket = $15 increase in price

Next, price of 120 blanket = Price of 150\ blanket + increase\ in\ price

Price\ of\ 120\ blanket = 32+15 = \$ 47

∴ $47 should be the price for at least 120 blanket to be sold.
