Your current schedule only lets you take two 1-credit courses every six months. You need 12 credits to get the degree you want.
lianna [129]
So,

Since you can only take two one-credit courses every six months, you can earn 2 credits every six months, and 4 credits in one year.  Multiplying that by 3, you get 12 credits in 3 years.

It will take 3 years to get the degree.

All of the following are ways to write 25 percent of N EXCEPT 0.25N 25N/100 1/4N 25N
Olin [163]
The last one would be incorrect. We are looking for PART of whatever N is. Multiply by the whole number 25 is definitely not what we want to do. 

Hope I helped!

Please give an explanation on how you got this answerI'm not sure if it's too late or what, but I can't get it.
Alona [7]
Step 1: multiple the second equation by 2 so that you get -1/4 for the coefficient of y, the same as in equation 1
equation 2 multiply by 2: 1/4 x - 1/4 y=38  ..........name this equation 3
subtract equation 1 from equation 3: (1/4 x -1/2 x)=38-10
-1/4 x = 28
x=-112
plug in x=-112 in any of the equation, you will get y=-264
so the answer is A
