Answer:
Step-by-step explanation:
(x - 2)/2 = 4
x - 2 = 8
x = 10
(y + 2)/2 = -3
y + 2 = -6
y = -8
(10, -8)
You can use Substitution to solve this problem:
4x-y=20
-y=-4x+20
y=4x-20
Now you have two equations, and you use the first one to substitute into the second one.
y=4x-20 and -2x-2y=10
-2x-2(4x-20)=10
-2x-8x+40=10
-10x+40=10
-10x=-30
-x=-3
x=3
Now that we have figured out what x is, we can substitute x in to one of the equations to figure out y.
4x-y=20 x=3
4(3)-y=20
12-y=20
-y=8
y=-8
<em><u>So your answer would be x=3 and y=-8</u></em>
Hello there!
On those type of angles, the angles that are facing each other is equal to another.
So you can set up the equation like this :
10x + 1 = 12x - 5
-2x = -6
x = 3
So the answer is x = 3.
In some problems, you have to find the angle.
Then you just simply substitute 3 into x.
10x + 1
10(3) + 1
30 + 1
31
12x - 5
12(3) - 5
36 - 5
31
The angles are 31° and 31°.
Hope this helped! :)
Answer:
¢40 or $0.40
Step-by-step explanation:
270 - 250 = 20
20 ÷ 50 = 0.4
Answer:
Therefore,
Distance between XY is 878 ft and YB is 524 ft.
Step-by-step explanation:
Given:
BW = 1612 ft
∠ Y = 72°
∠ X = 49°
To Find:
XY = ?
YB = ?
Solution:
In right angle Triangle Δ WBY Tangent identity,
Substituting we get
Similarly,
In right angle Triangle Δ WBX Tangent identity,
Substituting we get
Now For
