Find the value of x. Round to the nearest tenth if necessary.
Answer:
x
Step-by-step explanation:
-3(x-4) = -9(x - 1)
X=?
Answer:
x = - 1/2
Step-by-step explanation:
-3(x-4) = -9(x - 1)
1. Distributive Property
-3 * x -3 *-4 = -9 * x -9 * -1
-3x + 12 = -9x + 9
Hint: 2 negatives make a postive
-3x + 12 = -9x + 9
2. Subtract 12 on both sides
-3x + 12 - 12 = -9x + 9 - 12
-3x = -9x + -3
3. Add 9x on both sides
-3x + 9x = -9x + 9x + -3
6x = -3
4. Divide both sides by 6 to isolate the variable
6x/6 = -3/6
x = - 1/2
Check:
-3(-1/2-4) = -9( -1/2- 1)
3/2 + 12 = 9/2 + 9
3/2 + 12 ( we need a common denominator so...lets make it 2 )
3/2 + 12*2/1*2
3/2 + 24/2 = 27/2 = 13 1/2 = 13. 5
Now...
9/2 + 9 ( we need a common denominator so..lets make it 2 )
9/2 + 9*2/1*2
9/2 + 18/2 = 27/2 = 13 1/2 = 13.5
13.5 = 13.5 CORRECT!
27/2 = improper fraction
13 1/2 = mixed number
13.5= decimal form

Which letter is in the solution set for graph #3
Answer:
N
Step-by-step explanation:
Since it says y is greater then 1 it would be above the red line.
Then for the next equation, it says that y is less than the equation so it is under the blue line.
Answer: The solution is (4,1)
Step-by-step explanation:
You can tell if it is a solution by looking at the point where the two lines intersect(meet). This is why the solution is (4,1).

x + 3y = 18
-X - 4y = -25
Answer:
x = -3
y= 7
Step-by-step explanation:
x + 3y=18 ----(1)
-x - 4y=-25 -----(2)
from equation (1)
x = 18 - 3y ---(3)
putting equation (3) into equation (2)
-(18 - 3y) - 4y = -25
18 + 3y -4y = -25
3y - 4y = -25 - 18
-y = -7
y = 7 ✓
Putting y=7 into equation (1)
x + 3(7) = 18
x + 21 = 18
x = 18 - 21
x = -3 ✓

Jeremiah plans on building a garden walkway 5 meters long with stones that measure 5/6 meter on each side. There will be no spaces in between. How many stones are needed?
Answer: 6
Step-by-step explanation:
From the question, we are informed that Jeremiah plans on building a garden walkway 5 meters long with stones that measure 5/6 meter on each side.
The number of stones that are need would be gotten by dividing 5 by 5/6. This would be:
= 5 ÷ 5/6
= 5 × 6/5
= 30/5
= 6
Therefore, the answer is 6.
