Write the algebra expression: six times the sum of four and a number

6(x+4)

Step-by-step explanation:

We want to write an algebraic expression for "six times the sum of four and a number"

Let's break this down.

The sum of four and a number:

The words "sum" indicates addition. We can call " a number" x, since it is unknown.

So, the sum of four and a number is: (x+4).

Six times:

The word "times indicates multiplication. We are multiplying six and the sum of four and a number.

So, we have: 6(x+4)

The algebra expression for "six times the sum of four and a number" is 6(x+4)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
