Answer:
the expression is: 
and 2730 different ways are possible.
Step-by-step explanation:
In the given question we have to choose a president, vice
president, and secretary.
Permutations are used when order is important so, as in the given question order is required. We would use permutations
The formula used is: 
where:
n=total number of objects
r=number of objects selected
In our case: n=15, r=3
Putting values and finding the answer:
So, the expression is:
and 2730 different ways are possible.
2/3 - 1/2x = -2/3 then the value of x is 6 .
The algebraic expression should often take one of the following forms: addition, subtraction, multiplication, or division. Bring the variable to the left and the remaining values to the right to determine the value of x. To determine the outcome, simplify the values.
The steps to use the calculator to determine x's value are as follows:
- Fill in the multiplicand and product fields with the numbers (Integer/Decimal Numbers).
- To obtain the result, press the "Solve" button now.
- The output field will show the dividend or the x value.
given equation is
2/3 - 1/2x = -2/3
⇒7/3-x/2 = -2/3
⇒7/3+ 2/3 =x/2
⇒9/3 = x/2
⇒ x=3 x 2
⇒ x=6
therefore the value of the x is 6

Answer:
y=44
Step-by-step explanation:
-x+y=27
-17+y=-27
27-(-17)=27+17
27+17=44
Answer is a right triangle. The angles of a triangle must add to 180 degrees.
You have two 45 degree angles
45 + 45= 90
Now you need 1 more angle to equal 180
180- 90= 90
A right angle is 90 degrees. A right triangle has one right angle and two acute.
