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})

Complete the sentence to explain how to use mental math to express 12/25 as a percent
Vlada [557]

Answer: It's 48%. See below.

Step-by-step explanation:

By definition, percent means out of a hundred. For instance, 10 percent is 10 out of 100.

One way to make \frac{12}{25} a percent is by making the denominator 100. In order to do so, multiply the numerator and the denominator by 4, since 25 times 4 is 100.

\frac{12}{25}  =  \frac{48}{100} = 48 %

This is very simple, and mental math is definitely possible. Hope this help.

Lots took one hour to drive from his apartment to philips arena and back. the return drive took 8 minutes less than the trip to
noname [10]

The equation would use to determine how long he drove each way is 2x - 8 = 60.

<h3>What is the equation?</h3>

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have been given that Lots took one hour to drive from his apartment to Philips arena and back. the return drive took 8 minutes less than the trip to the arena.

Since the return trip took 8 minutes less, the complete equation must be written in minutes.

Here x - 8 represents the time it took to return to Philips Arena.

The total travel time, including both directions, was 60 minutes;

thus, add x and x - 8 and set them both equal to 60.

So 2x - 8 = 60

Therefore, the equation would use to determine how long he drove each way is 2x - 8 = 60.
