Answer:
x = 5
Step-by-step explanation:
Using the fact that line segments AB and BC are parts of the whole line segment AC, we can write the following equation:
AB + BC = AC
Now, using the given values, we can substitute in for the equation and solve for x:
AB + BC = AC
9 + 2x - 5 = x + 9
2x + 4 = x + 9
x = 5
Thus, we have found that for these sets of equations for these line segments, our value for x should be 5.

Step-by-step explanation:
Question 3: (4, -3)
Solving through elimination: Multiply the first equation by -3.
-3x+6y=-30
3x-5y = 27
Add. The x drops out.
y= -3
Substitute -3 in for y.
x-2y=10
x-2(-3)=10
x+6=10
x=4
Question 4: (2,5)
Solve through elimination: Multiply the second equation with 3.


3/2= 6/4
15/4x=7.5
x=2
3/2 (2) + y = 8
3+ y =8
y=5
Question 5: (6,4)
Use your graph to graph.

Slope of -1/3
Y-intercept of 6 (0,6)
X-intercept of 18 (18,0)

Slope of 3/2
Y-intercept of -5 (0,-5)
X-intercept of

<span>first stack = 12 blocks second stack = 12 + 3 = 15 blocks third stack = 15 - 7 = 8 12 + 15 + 8 = 35 blocks

Well u have to have 2 cases a day witch is 300 150+150 then times it by 7 days its 2100 bars so 2 cases would be 1050 ? I think I'm sure
