Answer:
<u>12 years</u>
Step-by-step explanation:
Let Kishor's present age be denoted by x.
According to the question :
- He will 3 times as old as he was 4 years ago after 12 years
Therefore, the equation is :
Solving :
- x + 12 = 3x - 12
- 3x - x = 12 + 12
- 2x = 24
- x = <u>12 years</u>
<u></u>
Hence, Kishor's present age is <u>12 years</u>.
To draw the 2 dimensional representation, we just "open" the box and flatten it. Once we have it opened, we find the area of each side and add them up for the total surface area. See the pic. Let me know if you have questions. :)
Answer:
An equation is a mathematical statement that shows the equal value of two expressions while an inequality is a mathematical statement that shows that an expression is lesser than or more than the other. 2. An equation shows the equality of two variables while an inequality shows the inequality of two variables.
Step-by-step explanation:
hope this helps!
You have to isolate x. First you start off by adding the like terms which is -3x and -x. By adding them you get -4x.
8 - 4x = 12
Then you subtract 8 on both sides since it is positive to isolate x.
-4x = 4
Then you divide -4 by both sides and get x=4/-4
4/-4 is simplified to -1 so the answer is x= -1
