Answer:

a and c are the correct answers

brainliest please

Step-by-step explanation:

simplify each equation and look for ones which solve to a simple numeric equality:

First equation solves to -3/7=-18/42...take a 6 from 18 and 42, and you get -3/7. -3/7=-3/7 which is true - that means that, no matter what value is inserted for x, a true equation will result = infinite number of solutions

Second equation simplifies to 3x=-30. Nope

Third equation simplifies to -18=-18 = infinite number of solutions

Fourth eq: 5=-7/2 = No solution

5th eq: 6.2x=-3.5-16.2 = nope

KATRIN_1 [288]

Answer:

The circumference of the yellow circle is 9\pi or 28.27cm^2 approximately, the circumference of the blue circle is 6\pi or 18.85m^2 approximately, the circumference of the green circle is 80\pi or 251.33mm^2 approximately, the circumference of the red circle is 5\pi or 15.71cm^2 approximately, and the circumference of the pink circle is 7\pi or 21.99cm^2 approximately.

Step-by-step explanation:

To find the circumference of a circle, you need to multiply the diameter of the circle and multiply it by \pi. In this case, the circumferences of the yellow circle are 9\pi or approximately 28.27cm^2, the circumference of the blue circle is 6\pi or approximately 18.85m^2, the circumference of the green circle is 80\pi or approximately 251.33mm^2, the circumference of the red circle is 5\pi or approximately 15.71cm^2, and the circumference of the pink circle is 7\pi or approximately 21.99cm^2.

Find the slope of the line that passes through the points (3,6) and (5, 3).<br> -3/2<br> 3/2<br> 2/3
Natalija [7]

Answer:

-3/2.

Step-by-step explanation:

To find the slope, we find the rise over run.

In this case, the rise is 6 - 3 = 3.

The run is 3 - 5 = -2.

The slope is 3 / (-2) = -3/2.

Hope this helps!
