If you distribute -5 to the things in the parenthesis you would get 10k-20 which is the same as -5(-2k+4)
8c-3d is the correct answer
40 hours at 10.10 per hour = 404
10.10 x 1.5 = 15.15 overtime pay per hour
15.15 x 8 = 121.20
404 + 121.20 = $525.20 total
The first fraction is 4 over 6, right? hopefully it is, i cant really see.
Basically, you can divide 4 and 6 by the same number, they have factors in common. They're both multiples of 2. if you divide them both by 2, you get 2 over 3, which is the <em>exact same amount as 4 over 6, it's just written in a simpler way. </em>the first answer is 2 over 3.
What numbers can both 10 and 15 be divided by? give it a try.
You only need to know one side, you can use , tan, sin, or cos of the angles to find the other 2 sides.
