13. Translate the following verbal phrase

Artyom0805 [142]

a) algebraic expression

$\frac{3+x}{5}=10$

b) Solve and find value of x

x=47

Step-by-step explanation:

We need to translate the following verbal phrase into an algebraic equation

The quotient of three more than a number and five is ten

Let the number be x

three more than a number is written as: 3+x

Since quotient is 10 so,

The algebraic expression will be:

$\frac{3+x}{5}=10$

Now, <u>solving to find value of x</u>

$\frac{3+x}{5}=10$

Multiplying both sides by 5

$\frac{3+x}{5}*5=10*5\\3+x=50$

Now Subtract -3 from both sides

$3+x-3=50-3\\x=47$

So, value of x=47
