First subtract y from both sides to isolate the variable.
25 = 2y-2
Next, add 2 to both sides.
27 = 2y
Last, divide by 2.
13.5 = y
The answer is A is the answer
Answer:
4 / 15
Step-by-step explanation:
The total number of ways 2 students can be picked is 15 * 14 = 210 because you have 15 students to begin with and after you pick one, you're left with 14 more to choose from.
The total number of ways a senior and a junior can be picked is 8 * 7 = 56 because there are 8 seniors and 7 juniors.
The probability will then be 56 / 210 = 4 / 15. Hope this helps!
Convert the mixed fraction to improper fraction
13 1/8 = 105/8 ; 12 1/3 = 37/3
105 x 37
——— -—— simplify (divide 105 & 3 by 3)
8 3
35 37
—— x (multiply)
8
1295/8 = 161 7/8 square feet
