-32
-12(-5) is 60
60+4 is 64
64/(-2) is -32 because two different signs is negative and the same sign is positive
Hope this helps
Answer:
x= -33/2 or x=-16.5
Step-by-step explanation:
Expand the bracket
6(2x+3) = 2(5x-3)
12x+18=10x-15
Bring like terms together
12x-10x=-15-18
2x=-33
x=-33/2
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
=
+ 
=
+ 
576 =
+ 169
= 576 - 169
= 407
x = 
= 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.
1. To answer the questions shown in the figure atttached, it is important to remember that the irrational number e is aldo called "Euler's number" and you can find it in many exercises in mathematics.
2. Then, the irrational number e is:
e=<span>2.71828
</span>
3. When you rounded, you have:
e=<span>2.718
</span>
4. Therefore, as you can see, the the correct answer for the exercise above is the option c, which is: c. 2.718
I think it's A. Sorry if I get it wrong.
