I don't understand this... please help :(

Answers

Answer:

Radius is the distance from the center of the circle to the edge (if you were to cut just a slice of pizza)

diameter is directly in the middle from one end to the other (if you were to cut the pizza in half)

this means that the diameter is DOUBLE the radius

circumference is the length of the outside of the circle (so the length of the pizza crust)

this one is tricky because to find circumference you need to do [tex]2\pi r[/tex] (r is the value of the radius)

so for problem 1 the radius is 3 cm (the line is equivalent to if you were trying to cut out one slice of pizza)

the diameter is DOUBLE the radius, so if you were to cut the pizza in half all the way it would be 6 cm

and the circumference ([tex]2\pi r[/tex]) is 2 * pi * 3 cm

because it says to round pi to 3.14, the circumference would be 18.84

which of these would be a helpful first step in solving the equation? check all that apply. 7x - 9 = 2x + 21

Answers

Answer: E. Subtract 2x

Step-by-step explanation:

Subtracting 2x would remove a bit from both equations, giving us 5x - 9 = 12. This would make it easier now that we only have one number on a side.

Hope this helps!

Subtract 2x because you need to get the x value on one side and number on the other

Solve each of the following equations. Show its solution set on a number line. Check your answers. 5−p+6=−8

Answers

Add 8 to 5 and 6 on the left side of the equation. Put p on the right side. Answer is 19=p

Answer:

p = 19

Step-by-step explanation:

5−p+6=−8

5 + 6 - p = -8

11 - p = --8

11 - 11 - p = -8 - 11

- p = -19

p = 19

You would plot a closed circle on the line that has the value of 19 on the number line.

What is the value of x in the figure? Enter your answer in the box.

Answers

Answer:

x = 65

Step-by-step explanation:

(2x +15)= 145

-15 -15 subtract 15 from each side

2x = 130130/2 = 65 therefore x=65

Okay so these are vertical angles, which means that they are going to be equal to each other, aka CONGRUENT.

This means that your equation is going to be:

2x + 15 = 145

Now let us solve that equation.
You are going to subtract 15 from each side, so subtract 15 from 15, and subtract 15 from 145, meaning that your new equation is going to be:

2x = 130

Now your are going to divide each side my 2. This means you are going to divide 2x by 2 and divide 130 by 2. This means:

x= 65.

Scale factor is used to find the coordinates depending upon whether the scale factor value is less than one or more than one.

Step-by-step explanation:

A scale factor is a number which scales, or increases, some amount. In the condition y = Cx, C is the scale factor for x. C is likewise the coefficient of x, and might be known as the steady of proportionality of y to x.

An object is augmented if the scale factor is more noteworthy than 1. An article is decreased if the scale factor is a division, under 1.
