She needs in total 40,000 votes, and from those 40,000, 4/5 need to be from senior citizens, now, 5/5 is a "whole", so 5/5 - 4/5 that leaves only 1/5.
therefore, of those 40,000 votes, 1/5 can be of non-senior citizens, how much is 1/5 of 40,000? well, is just their product,
Answer:
x = 4, y = 1
(4, 1)
Step-by-step explanation:
-2x - y = -9
5x -2y = 18
-2x - y = -9
+2x +2x
-y = 2x - 9
/-1 /-1
y = -2x + 9
5x -2y = 18
5x - 2(-2x + 9) = 18
5x + 4x - 18 = 18
9x - 18 = 18
+ 18 + 18
9x = 36
/9 /9
x = 4
Now, we solve for y:
-2(4) - y = -9
-8 - y = -9
+ 8 +8
-y = -1
/-1 /-1
y = 1
(x, y) -> (4, 1)
Hope this helps!
Answer:
Step-by-step explanation:
First what we must do is rewrite the table to find a solution:
0.25^x −0.75x+1
64 3.25
16 2.5
4 1.75
1 1
0.25 0.25
0.0625 −0.5
0.015625 −1.25
We see where the values of the function are the same:
x = 0 (1)
x = 1 (0.25)
answer:
x = 0
x = 1
Answer:
I got x= 2.25
Step-by-step explanation:
X - 3 > 7
x > 7 + 3
x > 10
answer x > 10
