3. In a class of 50, the # of people with brown hair is 2 more than 5 times the number of people with red hair. How many
shtirl [24]

Answer:

8 red haired and 42 brown haired

Step-by-step explanation:

I chose a random number to start off with (which is 8) and I multiplied it by 5.

8•5=40 and then you have to add 2, so you get 42.

42+8 = 50

The equation would be (5x+2)+x where 'x' is the number of people with red hair.

A circle is centered at the point (-3,2) and passes through the point (1,5). What is the radius of the circle?
Akimi4 [234]

Answer:

5

Step-by-step explanation:

The radius is a distance on a circle from the center to a point on the circle.

We have both of these points describe here in this definition.  Using the distance formula will give us the radius.

\sqrt{(x \text{ difference })^2+(y \text{ difference})^2

The difference between 1 and -3 is 1-(-3)=4.

The difference between 5 and 2 is 5-2=3.

\sqrt{4^2+3^2}

\sqrt{16+9}

\sqrt{25}
