I am pretty sure your answer will be 96783564.8, but it may need to be rounded. If I am wrong, I am sorry.
Hope this helps~!
The answer would be 39.78
I believe x is 43.
3x+17+x-9=180 It is 180 because a straight line is 180 degrees
4x+8=180
-8 -8 subtraction property of equality
---------------
4/4x=172/4 division property of equality
x=43 solution
Answer:
2. 1/2
Step-by-step explanation:
slope is rise over run
y2-y1/x2-x1
7-5/6-2 = 2/4 = 1/2
Answer:

- Coordinates (x, y)
- Systems of Equations
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
8x + 3y = 20
x + 4y = 17
(1, 4)
<u>Step 2: Check</u>
<em>Plug and verify the coordinates is a solution.</em>
- Substitute in point [1st Equation]: 8(1) + 3(4) = 20
- Multiply: 8 + 12 = 20
- Add: 20 = 20

- Substitute in point [2nd Equation]: 1 + 4(4) = 17
- Multiply: 1 + 16 = 17
- Add: 17 = 17

∴ Since both equations work out, (1, 4) is a solution to the systems of equations.
