9/11=x/22
11*2=22
9*2=x
x=18
9/11=18/22
2x + 2y=132
xy=1080
Let x=1080/y
2160/y + 2y=132
2y^2 - 132y +2160=0
2(y^2-66y+1080)=0
2(y-30)(y-33)=0
y=30 or y=33
(36,30) or (30,36)
So... x=30,36 and y=36,30. Either way, the answer is 30 by 36 or 36 by 30.
Percent decrease : (original number - new number) / original number...x 100
percent decrease = (25 - 18) / 25....x 100
percent decrease = 7/25 * 100
percent decrease = 700/25 = 28%
Answer:
see explanation
Step-by-step explanation:
The set of the first few prime numbers are
2, 3, 7, 11, 13, 17, 19, 23 ...............
Considering the odd primes, then
24 = 7 + 17
36 = 13 + 23
Answer:
1/2
Step-by-step explanation:
you the x and the y intercepts!
the X intercept is (4,0) and the Y intercept is (0,-2)
and in having those two intercepts, it made solving for the slope a whole lot easier!!!
heres what you do:
<u>-2 - 0 = -2</u>
0 - 4 = -4
and that can be simplified down to 1/2 :D
<em>i wasn't quite sure what the numbers you put in the question were, so i just looked at the picture :D hope this helps!!! </em>
