Answer:
x ≤ -7
Step-by-step explanation
<em>the steps to solve this are:</em>
1. Add 10 to both sides to get the x value and constant isolated on both sides.
-2x ≥ 14
2. Divide both sides by -2 to get the x value
x ≥ -7
3. Flip the inequality sign since you divided by a negative x-value.
x ≤ -7

Answer:
The length of prism is <u>9 centimetres</u>.
Step-by-step explanation:
Given:
The volume of a rectangular prism is 72 cubic centimeters.
The prism is 2 centimeters wide and 4 centimeters high.
Now, to find the length of prism:
Let the length be
.
Width = 2 centimeters.
Height = 4 centimeters.
Volume = 72 cubic centimeters.
So, putting the formula to get the length of prism:



Dividing both sides by 8 we get:

Length = 9 centimetres.
Therefore, the length of prism is 9 centimetres.
Answer:
x=11 (read below)
Step-by-step explanation:
7 + x = 18
<em>Subtract 7 from both sides</em>
x=11
It's quite simple because if you do something to one side of the equation, you need to do it to the other because otherwise the equation won't be equal. This is how you need to simplify most problems, by taking something from one side and taking from the other as well.
3/5 i believe. if you take 7 and divide it by 2 its 3.5.
7. 20
8. 680
9. 700
10. 4,000
11. 106,000
12. 5,800
