Answer:

The third table.

Step-by-step explanation:

To have a proportional relationship there must be a constant rate of change

6-5 / 9-7 = 1 /2

5-3 /7-4 = 2/3

these are different so this is not a proportional relationship

10-8 /150-120 =2/30

8-5 /120-75 =3/45

these are different so this is not a proportional relationship

10-8 /12-10 =2/2 =1

8-6 /10-8 =2/2= 1

These are the same therefore it is proportional

The sum of three consecutive even numbers is 306. Find the three numbers.​
zysi [14]

Answer:

100, 102, 104

Step-by-step explanation:

Hi there!

Let <em>x</em> be equal to the first number in the set of the three consecutive even numbers.

We're given that the sum of three consecutive even numbers is 306.

Because <em>x</em> is the first number, the next would be <em>x</em>+2, and then <em>x</em>+4. These are our even numbers.

We can now set up an equation:

(x)+(x+2)+(x+4)=306

Combine like terms:

x+x+x+2+4=306\\3x+6=306\\3x=300\\x=100

Therefore, the first number in the set of 3 numbers is 100.

The next two even numbers after 100 is 102 and 104.

Therefore, the three numbers are 100, 102 and 104.

I hope this helps!

I’m confused on this one
DanielleElmas [232]

The answer is C! For point "M" to move 180 degrees it has to move left as it's positioned on the right side for now. This eliminates answers A and D. Now, be sure to pay attention the trapezoid. Normally when shapes rotate 180, they completely flip and their coordinates are now located at different sides. Also, it is located at the "half-way mark" you can say. The answer is not B as the shape moved 270 degrees. Hope this helped :))
