Hmm, I believe the answer is 80%.
It is a decrease.
30 - 6 = 24.
24/30 = 80% decrease from Wednesday.
7x+1y = 17.00 can be simplified to y = -7x +17
<span>-7x +17 can then be substituted for y in 3x+ 4y =17.50
</span>3x+4(y) = 17.50
3x+ 4(-7x +17) = 17.50
From here you can solve for X
<span>3x + 4(-7x +17) = 17.50
</span>3x -28x + 68 = 17.50
-25x + 68 = 17.50
-68 -68
-25x = -50.50
÷-25 ÷-25
X = 2.02
You can then replace x with 2.02 in the original 7x + 1y = 17.00 to solve for y.
7(x) + 1y = 17.00
7(2.02) + y = 17.00
14.14 + y = 17.00
-14.14 -14.14
y = 2.86
Then substitute 2.02 for x and 2.86 for y in the original 3x+ 4y = 17.50 to check.
3(x) + 4(y) = 17.50
3(2.02) + 4(2.86) = 17.50
6.06 + 11.44 = 17.50
17.50 = 17.50
So
X = 2.02
and
Y = 2.86
or the solution set is (2.02, 2.86)
Hope this helps
Answer:6
Step-by-step explanation:
You do 6/2 first which is 3 then you subtract 3 from 4 which is 1. Then you multiply 1 by 2 which is 2 and the last step would be multiplying 2 by 3 which is 6
Answer:
57.6......
Step-by-step explanation:
v=lxbxh...........
(3,6)(-2,1)
slope = (1 - 6) / (-2 - 3) = -5/-5 = 1
point slope form : y - y1 = m(x - x1)
slope(m) = 1
(3,6)....x1 = 3 and y1 = 6
now we sub
y - 6 = 1(x - 3) <===
