Answer:
Step-by-step explanation:
You need to analize the figure carefully in order to understand the information given in the exercise.
According to the data given, you know that the lenght of the side BD of the triangle ABD is:
You can notice in the figure the lenght BD is the sum of the lenght BC and the lenght CD.
Knowing that, you can can write the following equation:
Since:
You can make the substitution into and then solve for "y" in order to find its value.
The result is:
Answer:
Step-by-step explanation:
All the three sides are equal. So, it is equilateral triangle.
All the angles are less than 90°, so, it is acute triangle
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:
Answer:
Yes
