Answer:
x = 34.06
Step-by-step explanation:
The sum of angles in the triangle LUV is 180 degrees
Given
∠L=(3x+y)°
∠U=42.6°
∠V=(4x−3y−0.8)°
Since ∠L+∠U + ∠V = 180 degrees
Substitute:
3x+y + 42.6 + 4x - 3y - 0.8 = 180
7x - 2y - 41.8 = 180
7x - 2y = 221.8 ... 1
Since UV = UL, hence the triangle is isosceles and <V = <L
3x+y = 4x-3y - 0.8
-x +4y = -0.8
x - 4y = 0.8 ....2
From 2: x = 0.8+4y
Substitute into 1:
7x - 2y = 221.8
7(0.8+4y) - 2y = 221.8
5.6 + 28y-2y = 221.8
26y = 221.8-5.6
26y = 216.2
y = 8.32
Get x
x = 0.8+4y
x = 0.8+4(8.32)
x = 0.8 + 33.26
x = 34.06
<em>Note that it was assumed that <V = <l since the question is not clear</em>
Answer:
x= -10
Explanation:
When solving for x with 2 equations given, you’d add 3x+10 with 7x-30 like so: 3x+10=7x-30. you ALWAYS work your way from right to left till you’ve got nothing on your right but a number with no variable, so subtract 7x with 3x, giving you 4x, so now your equation would be: 4x+10=-30. Now that there is a single number to the right, you start to rotate, so subtract 10 from -30, giving you -40, so now your equation would be: 4x=-40. This is the last step, so all you have to do is divide 4x to itself and to -40. You DO NOT add the variable x to your answer, so it should be: x=-10 as your final answer.
Answer:
x = -1
y = -2
Step-by-step explanation:
5x + 2y = -9 2y = -9 - 5x y=(-9-5x)/2
3x + 4y = -11
3x+4[(-9-5x)/2] = -11
3x+( -36-20x)/2 = -11
3x-18-10x = -11
-7x = 7
x = -1
y = -2
