Can someone explain how to do this and add the formula please
lisabon 2012 [21]

Answer:

5 is 35 and 6 is 50

Step-by-step explanation:

To solve 5, you need to know how many degrees is the line, which is 180 because lines are 180 degrees. You then subtract 110 from 180 which equals to 70. What you have left now is 2k. A number times 2 will equal to 70, so k=35.

For 6, if you ever see two lines intersecting each other, it means that it is 360 degrees. We already have one angle, which is 120. The other angle is d+70 degrees, and any angle that is reflecting the other angle will have the same value. So, d equals 50

What number is 24% of 75
maria [59]
Remember that a percentage means "parts out of 100".  24% in decimal form is therefore 0.24, because it is 24 out of the possible 100, or 1.0.  To find 24% of 75, you just multiply 0.24 times 75:

75 x 0.24 = 18
