Which of the following equations has the same solution as the equation 3x+2y= -12?

1 answer:

5 0

-3x - 2 = 12 is the answer
Take the original problem and input (-2,-3)
3(-2) + 2(-3) = -12
-6 + -6 = -12
Now input into new problem:
-3(-2) - 2(-3) = 12
6 + 6 = 12

Answer:

Part 1 : Equation: ( 3x - 9 ) + 30 + 24 = 180,

Part 2 : Value of x ⇒ 45°,

Part 3 : Measure of Angle U ⇒ 126°

Step-by-step explanation:

~ Part 1 ~

We know that ∑ of angles in a triangle is 180;

m∠ U + m∠ V + m∠ W = 180°,

Equation: ( 3x - 9 ) + 30 + 24 = 180

~ Part 2 ~

Now let us simplify the equation above to solve for x;

3x - 9 + 30 + 24 = 180,

3x - 9 = 126,

3x = 135,

x = 45 degrees ( ° ) ⇒

Value of x ⇒ 45°

~ Part 3 ~

If it is known that m∠ U ⇒ 3x - 9;

m∠ U = 3 * ( 45 ) - 9,

m∠ U = 135 - 9,

m∠ U = 126 degrees ( ° ) ⇒

Measure of Angle U ⇒ 126°

What is the length of MN

rusak2 [61]

Answer:

C. 5

Step-by-step explanation:

∆LMN kid an isosceles triangles because it has two base triangles that are equal to each other. Therefore, the sides opposite the base triangles would also be equal to each other.

Thus:

3x = x + 10

Solve for x. Subtract x from each side

3x - x = 10

2x = 10

Divide both sides by 2

x = 5
