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

How to find the measure of angles?
nevsk [136]

Answer:

The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.

Carlos used 6 boards to build 2/3 of a front porch. How many boards will Carlos use to build the whole porch? Express your answe
antiseptic1488 [7]

Answer:

9 boards

Step-by-step explanation:

2/3 of the porch= 6 boards

so to figure out how much one third of the porch needs you find half of what it takes to fill in 2/3 of the porch and you get 3.

so 3=1/3 of the porch

then you simply do 3times 3 or 3+3+3 and you get 9

so it takes 9 boards to fill the whole porch
