Question

Match the following statements on the left hand side with their correct expressions on the right hand side.

• A. 3A
• B. 2X - 12
• C. $\frac{Y}{2}-5$

Answer 1

Take the number as A.

First, multiply 2 with A.
We will get $2\times A=2A$

Again, multiply with 3.
So, we will get $2A\times 3=6A$

On dividing it by 2, we get $\frac{6A}{2}=3A$

So, the expression for the statement "Take a number A, Multiply 3 with two times A, Now, half what you have." will be 3A.


Take the number as X.
On subtracting 6 from it, we will get $X-6$

Now, when we have to double the answer, the expression will be: $2(X-6)=2\times X-2\times 6=2X-12$

So, the expression for the statement "To any number X, subtract 6 from it and double the answer " will be 2X - 12.


To the number Y, when we divide by 6, we will get:
$\frac{Y}{6}$

Now, you multiply it by 3.
We will get: $\frac{Y}{6}\times 3=\frac{Y}{2}$

Finally subtracting 5 from $\frac{Y}{2}$, you will get:
$\frac{Y}{2}-5$

So, the expression for the statement "Divide a number Y by 6. Multiply the answer by 3 and subtract 5 from it. " will be $\frac{Y}{2}-5$
