The number of folders and notebooks in the equation is given by 3 and 5 respectively.
<h3>How to find number of folders and notebooks?</h3>
let
- x = number of folders
- y = number of notebooks
The equation:
x + y = 8
0.50x + 1.0y = 6
From (1)
x = 8 - y
Substitute x = 8 - y into (2)
0.50(8 - y) + 1.0y = 6
4 - 0.50y + 1.0y = 6
4 + 0.40y = 6
4 - 6 = -0.40y
-2 = - 0.40y
y = -2 / 0.40
y = 5
Recall
x + y = 8
x + 5 = 8
x = 8 - 5
x = 3

Step-by-step explanation:
Answer:
Step-by-step explanation:
to find the inverse first switch the x and y
y=log(x+3) inverse is x=log(y+3)
then change to exponential form to solve
turns to
a is 10
b is y+3
c is x
subtract 3 from both sides
Answer:
0.5152
Step-by-step explanation:
Answer: x
Step-by-step explanation:
