Answer:
68.875 / 7.25 = 9 1/2 pounds
Step-by-step explanation:
We are to find the value of
First we need to find the inverse of f(x) . The inverse of
is
.
Steps to find inverse of f(x) are shown below in the image.
So
=
Therefore, the correct answer is option C
The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6
In order to solve this let us for at assume that the value of the width is X. Therefore the length will be x+5.
We can now write an equation:
(X+5) + (X+5) + X + X = 58
Combining like terms we should get
4X + 10 = 58
Now subtract 10 from both sides to get
4x = 48
Divide by 4 now and you should get
X = 12
Now we know the value of X and therefore the width.
Answer:
19.206
Step-by-step explanation:
First you need to find out 10% of 18.
You can do that by 18/100 which is .18.
Then multiply that by 10 which is 1.8 (10% of 18)
His hourly rate decreased by 3% AFTER his raise so you would find 3% of 19.8 and not 18.
You do the same process and divide 19.8/100
Then multiply this by 3 and you can get 0.594
That is how much his raise decreased by so you would subtract it from 19.8
19.8 - 0.594 = 19.206 (Round if needed)
Hope this helps
