ANSWER: ( 0.75 , 2 )

EXPLANATION:
To find the system of solutions, solve the 2 equations.
(1) Find what you can multiply with to get the same number in the second equation.
(2) Multiply equation by -2
(3) New equation:
-4x - 2y = -6
3x + 2y = 8
(4) Add both equations
(5) New equation:
7y = 14
(6) Divide both sides by 7
(7) New equation:
Y = 2
-
Now find X
(1) Substitute y with a equation
(2) 3x + 2 (2) = 8
(3) 3x + 4 = 8
(4) Subtract 4 both sides
(5) 3x = 4
(6) Divide 3 both sides
(7) x = 0.75

The legs of a isosceles triangle are 0.3 foot less then twice the base . The perimeter of the triangle is 4.9 feet .
kicyunya [14]
<h2>Greetings!</h2>

Answer:

The legs are 1.9 feet long

And the base is 1.1 feet long.

Step-by-step explanation:

Firstly, you need to find the value of x.

You need to add all the sides together:

2x - 0.3 + 2x - 0.3 + x

Simplified =

5x - 0.6

And this equals 4.9:

5x - 0.6 = 4.9

Next, you need to move the -0.6 over to the other side, making sure to make it a positive:

5x = 4.9 + 0.6

5x = 5.5

Now divide each side by 5:

\frac{5x}{5} = \frac{5.5}{5}

x = 1.1


As the image is unclear of what side you are finding the length of:

2x - 0.3 = 1.9 feet long

And the base is 1.1 feet long.

Describe how to determine if a number is a solution to an equation.
marin [14]

Step-by-step explanation:

Determine whether a number is a solution to an equation.

Substitute the number for the variable in the equation.

Simplify the expressions on both sides of the equation.

Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.
