Double the sum of a double the number and quotient of five and two

Vika [28.1K]

Answer:

The required expression is $2(2x+\frac{5}{2})$

Step-by-step explanation:

Let the number be x

We are supposed to write the algebraic expression of given statement

Double the number = 2x

Quotient of five and two = $\frac{5}{2}$

Now we are given that Double the sum of a double the number and quotient of five and two

So, Sum of a double the number and quotient of five and two = $2x+\frac{5}{2}$

So, Double the sum of a double the number and quotient of five and two = $2(2x+\frac{5}{2})$

Hence The required expression is $2(2x+\frac{5}{2})$

2. Divide both sides by 2
v - 4/2 = t
3. Switch sides
t = v - 4/2
