Answer:
32d
Step-by-step explanation:
-The students ride their bikes to and from school every day. The distance is thus;
-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:
Now, we multiply the distance per day by the total number of days:
Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).
For this case we must propose an algebraic expression associated with:
"four times a difference of a number and seven is 12"
So we have to:
Four times a difference of a number and seven is represented as: 
So we have the expression is:
We apply distributive property to the terms within parentheses:
We add 28 to both sides:
We divide between 4 on both sides:
Answer:
The original number is 15.
Let’s work it out.
First, divide.
21 divided by 3 is 7.
Now, add.
8 + 7 = 15
This is true because...
15 - 8 = 7
Hope this helps, have a great day, stay safe and positive.
