Answer: 3,75 ( 15/4)
Step-by-step explanation:
1/3 (6y - 9) = -2y + 13
6y/3 - 9/3 = - 2y + 13
2y - 2 = - 2y + 13
2y + 2y = 13 + 2
4y = 15
y = 15/4
y = 3,75
Lucy has 20 questions in her science home work
<em><u>Solution:</u></em>
Given that,
Lucy correctly answered 70% of the questions on her science homework
She counted 14 correct answers on her paper
<em><u>To find: Number of questions in her science home work</u></em>
Let "x" be the number of questions in her science home work
From given we can say,
Lucy correctly answered 70% of questions
She counted 14 correct answers
70 % of total questions = 14 correct answers
70 % of x = 14
Thus Lucy has 20 questions in her science home work

Answer:
The window should be positioned 4 1/8 feet far from each edge of the wall.
Step-by-step explanation:
Since a construction crew is placing a square in a wall for a new window, which is 3 1/8 feet wide, while the wall has a length of 11 3/8 feet, and the crew wants to position the window at the center of the wall, to determine how far from each edge of the wall should the window be positioned, the following calculation must be performed:
1/8 = 0.125
3/8 = 0.375
(11,375 - 3,125) / 2 = X
8.25 / 2 = X
4.125 = X
Therefore, the window should be positioned 4 1/8 feet far from each edge of the wall.
