Answer:
Step-by-step explanation:
1. let x be the unknown number.
-Given that 24 divided by x is less than x is less than 7 means that 7 is greater than the quotient thereof.
-The in equality is written as:
2.Let the amount Chris has be y.
-At most is a term of inclusivity implying less than or equal to a specified quantity.
-$5 less than twice y will therefore be represented as:
3. It is clear that the minimum age to have a drivers license is 16.
-Let x be the age of a driver whose age is unknown.
-It is therefore obvious that all drivers in Ohio are either exactly 16 years or older.
-Our inequality symbol is that of equal to or greater than, thus:
4. let x be the number of CD's bought and y of DVD's bought.
-CD's are priced at $14 each and DVD's at $16 each, given a budget of $65.
-They can only buy a number of units whose price is less than or exactly $65, thus:
Let's call the width and the length
based on this, we can make two equations based on the first and second sentences in the problem.
If we substitute for
into the second equation, we can make the following:
- Substitute
- Use the Distributive Property
- Combine like terms
- Subtract 4 from both sides
- Divide both sides by 4 and simplify
Now, let's find :
The length of the rectangle is and the width of the rectangle is
.
