Answer:
This captain could select 350 different teams.
Step-by-step explanation:
The order in which the girls and the boys are picked is not important. For example, picking Daniela and Laura is the same as picking Laura and Daniela. So we use the combinations formula to solve this question.
Combinations Formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Girls:
2 from a set of 5. So
[tex]C_{5,2} = \frac{5!}{2!(5-2)!} = 10[/tex]
Boys:
3 from a set of 7. So
[tex]C_{7,3} = \frac{7!}{3!(7-3)!} = 35[/tex]
Total:
[tex]10*35 = 350[/tex]
This captain could select 350 different teams.

Solve the system of linear equations by elimination x−2y=−7 3x+2y=3
The solution of this system of linear equations is (3,13)
What is the solution to a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here: x−2y=−7 & 3x+2y=3
Thus solving these two equations we get -8y=-24 or y=3
Therefore x=13
Hence, The solution of this system of linear equations is (3,13)

answers:
50%
10%
90%
100%
What is the value of X
Answer:
the answer is 70.
Step-by-step explanation:
Since x and 80 are non-adjacent co-interior angles with respect to ( 2x +10 )
So,
x + 80 = 2x + 10 ( sum of two non-adjacent co-interior angles is equal to the exterior angle of that triangle )
=> 80 - 10 = 2x - x *( switching sides of x and 10 )
=> 70 = x
So, the value of x is 70
x + 80 = 2x + 10 (exterior angle property)
2x -x = 80 -10
x = 70

If AD = 12 and AC = 4y-36, find the value of y
Answer:
y=12
Step-by-step explanation:
in that case, then 12 = 4y -36
12 =4y -36
12+36=4y
48=4y
48/4=y
12=y
answer :y=12
Answer:
y = 15
Step-by-step explanation:
Consider that the attached screenshot is the figure given in the problem. Also consider that DC = 12, due to the fact that AD = 12, and there is a midpoint at point D.
AD + DC = AC
12 + 12 = 4y - 36
24 = 4y - 36
+ 36 + 36
60 = 4y
60/4 = 4y/4
y = 15
Which statement is true?
Answer:
Step-by-step explanatmkjion:
The Correct statements is [tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex].
To determine which statement is true, let's evaluate each statement one by one:
[tex]\sqrt[m]{x} * \sqrt[m]{y} = 2\sqrt[m]{xy}[/tex]
This statement is false. The correct product of two nth roots ([tex]\sqrt[m]{x}[/tex] and [tex]\sqrt[m]{y}[/tex]) is [tex]\sqrt[m]{x*y}[/tex], not 2[tex]\sqrt[m]{x*y}[/tex].
[tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex].
This statement is true. When raising an nth root to a power, you can simply multiply the exponents. So, [tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex]..
[tex]a \sqrt[n]{x}+ b \sqrt[n]{x} = ab \sqrt[n]{x}[/tex]
This statement is false. The correct result of adding two nth roots is not the product of the coefficients. It's simply (a + b) [tex]\sqrt[n]{x}[/tex].
[tex]\sqrt[m]{x} /\sqrt[m]{y} = \sqrt[m]{xy}[/tex]
This statement is false. The correct division of two nth roots ([tex]\sqrt[m]{x}[/tex] divided by [tex]\sqrt[m]{y}[/tex]) is not equal to the product of the roots. The correct division is:
[tex]\sqrt[m]{x} /\sqrt[m]{y} = \sqrt[m]{x/y}[/tex]
So, [tex]\sqrt[m]{x} /\sqrt[m]{y}[/tex] is equal to [tex]\sqrt[m]{x/y}[/tex], not [tex]\sqrt[m]{xy}[/tex].

[tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex]

Solve the system of equations -x+y=15−x+y=15 and -5x-3y=27−5x−3y=27 by combining the equations
Answer:
Solution: x= -36, y=51
Step-by-step explanation:
Solve the system:
x + y = 15
-5x - 3y = 27
By using the reduction method.
Multiply the first equation by 3:
3x + 3y = 45
Add it to the second equation:
3x - 5x = 45 + 27
Simplifying:
-2x = 72
Dividing by -2:
x = 72/(-2)
x = -36
From the first equation:
-36 + y = 15
Adding 36:
y = 15 + 36 = 51
y = 51
Solution: x= -36, y=51

Study this incomplete image of a geometric construction. This image may result from the construction of ____
A. a line parallel to line AB through C.
B. a perpendicular to line AB.
The next step in this construction is to set the compass width to
A. line segment DC and draw an arc centered at D intersecting the second arc.
B. line segment KC and draw an arc centered at K intersecting the second arc.
C. arc IJ and draw an arc centered at K intersecting the second arc.
D. line segment CI and draw an arc centered at I intersecting the second arc.
Thank you.
Answer:
A line parallel to line AB through C & arc IJ and draw an arc centered at K intersecting the second arc
Step-by-step explanation:
This image may result from the construction of a line parallel to line AB through C.
The next step in this construction is to set the compass width to arc IJ and draw an arc centered at K intersecting the second arc.
What is Construction?Geometric constructions are precise drawings of geometrical shapes, angles, and lines. We will need a pencil, a ruler (or other straight edge), and compasses to do this.
Given:
From the image we can see that there is an attempt to make a copy of angle and proceeds to draw a parallel line.
So, This image may result from the construction of a line parallel to line AB through C.
Now, the next step can be measure the arc IJ from compass and put the pointer on K with same measurement and cut the Arc.

Answer:
(4 , -3)
Step-by-step explanation:
Put "y" by itself on one side to isolate it
3x - y = 15
3x = 15 + y
3x - 15 = y
Substitute "y" in the second equation for "3x - 15"
x + (3x - 15) = 1
4x - 15 = 1
4x = 16
x = 4
Then, plug 4 into x in any of the equations
4 + y = 1
