Which of the following is an open statement?
3 + 10 = 13
2x + 5x = 7x
14 ÷ 2 = 7
3x = 12

Answers

Answer 1
I think the last one because a open statement contains at least one blank that becomes true or false when it’s filled in if you fill x with 4 you will get 3(4) 3*4=13 so if that blank was filled in with 4 it would be true
Answer 2

Answer:

3x = 12

60 is mirrored to 4x. meaning both are the same value

60 × 2 = 120

360 - 120 = 240

Since m and it's mirrored angle are equal value, then

240 ÷ 2 = 120

answer is 120

Answer:

120°

Step-by-step explanation:

KML and HMG are equal. So 60 + 60 = 120.

The entire angle is 360°

360 - 120 = 240

The other two angles equals 240°

To find KMH (one of the angles) do:

240/2 = 120°

explain how to find the slope of a line through two points on a table

Answers

Answer:

you use slope formula m=y2-y1/x2-x1

m=21-11/5-3=15.8

Step-by-step explanation:

so the 3 points you have are (-1,-9) (3,11) (5,21)

so i'm going to choose (3,11) and (5,21) 3 is x1 11 is y1

                                                                5 is x2 11 is y2

m=y2-y1/x2-x1

m=21-11/5-3=15.8

good luck :)

hopefully, this helps

Take both coordinates (x,y) and use the formula y-y/x-x.

1)What if you have two equations equal to y? How do you solve for x?
2)If you need to solve for a variable to substitute, what is your first step?
3)What does it mean to substitute for a value?

Answers

Answer:

Step-by-step explanation:

If you have two equations for y, eliminate y by setting these two equations equal to one another.  Solve the resulting equation for x.  Then substitute your x value into one of the equations for y.  Write your solution as (x, y).

2)  If you need to solve for a variable to substitute, what is your first step?  Example:  If you have two equations for y, eliminate y by setting the two equations equal to each other.  This decides for you that you must solve for x.

3)  What does it mean to substitute for a value?  Example:  If you have y = 3x and 2x + y = 17, replace y in the second equation with 3x.  This eliminates y and allows you to solve for x.

Which shape shows the cross-section of the square pyramid when it is cut by a plane parallel to the base?

A.


B.


C.


D.

Answers

Answer:

It is the square (I'm assuming that one is D)

Step-by-step explanation:

Note that it specifically states that it is a "square pyramid". This means that the base is a square, and the other 4 sides create the pyramid.

Also note that the cross-section cuts by a plane "parallel to the base", suggesting that it will have the same shape as the base.

Since the base is a square, ∴ the plane cross-section will also be a square.
