It is convenient to follow directions. Create a chart with activities as column headings. Since the data is divided according to gender, you would put gender on the row headings. Fill in the given numbers (black), and make the totals come out (blue).
The numbers in the row total column are exactly that: the total of the numbers in the row. (A spreadsheet can do the actual addition or subtraction for you.)
Answer:
y = 0.3
Step-by-step explanation:
Solve for y:
(3.2y - 1.8) - (5.2 y + 3.4) = -5.8
-(5.2y + 3.4) = -5.2y - 3.4:
3.2y - 1.8 -5.2y - 3.4 = -5.8
Grouping like terms, 3.2y - 1.8 - 5.2y - 3.4 = (3.2y - 5.2y) + (-1.8 - 3.4):
(3.2y - 5.2y) + (-1.8 - 3.4) = -5.8
3.2y - 5.2y = -2 y:
-2y + (-1.8 - 3.4) = -5.8
-1.8 - 3.4 = -5.2:
-5.2 - 2y = -5.8
Add 5.2` to both sides:
(5.2 - 5.2) - 2y = 5.2 - 5.8
5.2 - 5.2 = 0:
-2y = 5.2 - 5.8
5.2 - 5.8 = -0.6:
-2y = -0.6
Divide both sides of -2y = -0.6 by -2:
y = 0.3
Step-by-step explanation:
it's obviously the equation is equals to zero,
-12x + 16 = 0
-12x = -16
-12. 12
like terms cancel each other to remaining with x
thus,
x = 4/3
<h2>AND</h2>4x - 12 = 0
4x = 12
4. 4
like terms cancel each other to remaining (make x subject of the formula) with x
thus,
x = 3
