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>
1) Answer: The part of the quadratic formula tells us whether the quadratic equation can be solved by factoring is b^2-4ac
2) 4x^2+6x+2=0
ax^2+bx+c=0; a=4, b=6, c=2
b^2-4ac=(6)^2-4(4)(2)=36-32
b^2-4ac=4
Answer: b^2-4ac=4
30 × 100 = 3,000, 30 × 10³ = 30,000 and 30 × 1000 = 30000. Therefore, options A, B, C and D are the correct answers.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
A) 30 × 100 = 3,000
Here, LHS = RHS
B) 30 × 10³ = 30,000
Here, LHS = RHS
C) 30 × 1000 = 30000
Here, LHS = RHS
D) 
30 × 10000 = 300,000
Here, LHS ≠ RHS
E) 30 × 10000 = 30,000
= 300,000
Here, LHS ≠ RHS
Therefore, options A, B, C and D are the correct answers.

105x + 7
so 105 divided by 7 = 15 só it should = 15 at the end of that equation
Answer:
I think it is 6/1
Step-by-step explanation:
You are wrong because 0.167 into a fraction is 167/1000 and that isn't one of the options but when I did it 1 1/2=3/2=1.5 and 1/4=0.25 so I did 1.5 divide by 0.25 and it gave me 6 so that why I think that my answer is correct and yours is not.
