Answer: Infinite solutions.

Step-by-step explanation:

y=-2x-6\\2y=-4x-12

Plug the value of y into the second equation.

\\ 2(-2x-6)=-4x-12\\-4x-12=-4x-12

Add 12 on both sides.

-4x-12+12=-4x-12+12\\-4x=-4x

Add 4x on both sides.

-4x+4x=-4x+4x

0=0

Answer:

Infinitely many solutions

Step-by-step explanation:

The equation, when set up will be  

2(-2x-6)=-4x-12  

-4x-12=-4x-12

   +12       +12  Add 12 to both sides

------------------------

-4x=-4x  Divide by -4 to both sides

 0=0 You get zero equals zero

Answer:

About 5.5% decrease

Step-by-step explanation:

Here, we want to calculate the percentage increase or decrease and its value.

The first thing to do here is to check if we are going to have a decrease or an increase.

since the value before the change is higher than the value after the change, then what we have is a decrease.

Mathematically, the percentage decrease is calculated as follows;

% decrease = (old value - new value)/old value * 100%

old value = 163 feet

new value = 154 feet

% decrease = (154-163)/163 * 100%

% decrease = -9/163 * 100%

% decrease = -5.52%

Thus the best answer is about 5.5% decrease

Find the measures of the angles of a triangle whose angles have a measure of x, 1/2x, and 1/6x. Also, what kind of triangle is i
Alexandra [31]

the sum of the angles in a triangle = 180°, thus

x + \frac{1}{2} x + \frac{1}{6} x = 180

multiply through by 6

6x + 3x + x = 1080

10x = 1080 ( divide both sides by 10 )

x = 108

the angles are 108°, 54° and 18°

Since all the angles are different and the largest is 108°

The triangle is an obtuse scalene triangle

Answer:

\frac{1}{4}

Step-by-step explanation:

Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;

5 x 4 = 20

If a color is selected at random the probability would be

\frac{part}{whole}

our part is 5

our whole is 20

so the probability would be;

\frac{5}{20} or \frac{1}{4} when reduced

Hope this helps!
