Solve the equation 14y+82=6x-20 for x if y is 25
Answer:
x= 226/3 or 75.33333333333333333333333333333
Step-by-step explanation:
14y+82=6x-20
y=25
Sub y=25 into 14y+82=6x-20
14y+82=6x-20
14(25)+82=6x-20
Calculate as follows:
14(25)+82=6x-20
350+82=6x-20
432=6x-20
Add twenty to both sides:
432+20=6x-20+20
452=6x-0
452=6x
Divide both sides by 6
452=6x
452/6=6x/6
452/6=x
x= 226/3 or 75.33333333333333333333333333333

Solve for x. Show all work.
9x
139°
71°
5х
92
Answer:
x = 17
Step-by-step explanation:
number of sides (n) = 5
Sum of angles of polygon = (n - 2) *180
= 3 * 180 = 540
9x + 71 + 92 + 5x + 139 = 540
9x +5x + 71 + 92 + 139 = 540
14x + 302 = 540
14x = 540 - 302
14x = 238
x = 238/14
x = 17

Answer:
x = [tex]\frac{85}{3}[/tex]
Step-by-step explanation:
From the figure attached,
ΔABC ~ ΔADE
Therefore, by the property of similar triangles corresponding sides of the given triangles will be proportional.
[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]
[tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]
[tex]\frac{12}{20}=\frac{17}{x}[/tex]
x = [tex]\frac{20\times 17}{12}[/tex]
x = [tex]\frac{85}{3}[/tex]

The math club is going to sell t-shirts as a fundraiser. They buy 100 t-shirts and pay a total of $600 for the t-shirts and printing costs.
If they sell each t-shirt for $12, how many t-shirts must they sell to make a profit of $300?
O A. 9
OB. 25
O C. 50
OD. 75
O E 100
They have to sell D. 75 shirts to make a profit of $300.
The total cost of buying and printing the shirts was $600.
In order to make a profit of $300, they would therefore have to raise:
= Cost + profit
= 600 + 300
= $900
As they are selling each shirt $12, the number of shirts they would have to sell to get to $900 is:
= 900 / 12
= 75 shirts
They would therefore have to sell 75 shirts in order to make a profit of $300.

Answer:
x = -1, and y = -2, giving you the answer (-1, -2)
Step-by-step explanation:
In the second equation, we're told that y is equal to 2x. With that, we can replace "y" in the first one with "2x", giving us:
-4x - 2x = 6
-6x = 6
x = -1
Now that we know the value of x, we can simply plug it into the first equation to find y:
-4x - y = 6
-4(-1) - y = 6
4 - y = 6
-4 + y = -6
y = -6 + 4
y = -2
So x = -1, and y = -2
