Ber [7]

Answer:

There are 8 males in the class and 42 females.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of females.

y is the number of males.

Class of 50 students

This means that $x + y = 50$

The number of females is 2 more than 5 times the number of males.

This means that $x = 5y + 2$

So, finding y, the number of males:

$x + y = 50$

$5y + 2 + y = 50$

$6y = 48$

$y = \frac{48}{6}$

$y = 8$

Females:

$x = 5y + 2 = 5*8 + 2 = 42$

There are 8 males in the class and 42 females.

Step-by-step explanation:

The distance in radical form is √100 (which is equal to 10units

Distance=√(-8--2)²+(7--1)²

D=√(-6)²+(8)²

D=√36+64

Converse: If line x and y are parallel then angles on the same line are supplementary angles.

Step-by-step explanation:

Converse:

Let's start with the converse, so if line x and y are parallel then angles on the same line are supplementary angles. I'm not sure if that's the converse your teacher wants but my teacher taught me this.

Finding x:

Now we know that the angles are supplementary angles, that means if w add them together we get 180°. So our equation will be $10x-22+3x+7=180$ . Now we just solve it. We start by combining like terms, then adding the 15 to both sides, and lastly we divide the 13 to both sides and get...
