Answer:
X=15
all you have to do is subtract 3 from 18 to get x
Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.

Answer:
30%
Step-by-step explanation:
30 blocks are shaded out of the 100
Answer:
The width is .16 miles and the length is .3 miles
Step-by-step explanation:
Use the area formula for a rectangle and the fact that the length = .14 + w. Your formula will look like this then:
.048 = w(.14 + w)
Distribute through the parenthesis to get
![.048=.14w+w^2](https://tex.z-dn.net/?f=.048%3D.14w%2Bw%5E2)
Get everything on one side of the equals sign and set the whole equal to 0:
![0=w^2+.14w-.048](https://tex.z-dn.net/?f=0%3Dw%5E2%2B.14w-.048)
Let's multiply everything by 1000 to get rid of those decimals:
![0=1000w^2+140w-48](https://tex.z-dn.net/?f=0%3D1000w%5E2%2B140w-48)
Now we need to factor that to solve for w:
w = .16 and w = -.3
Since the two things in math that will never ever be negative are distance measures and time, we can safely disregard the -.3. That means that the width is .16 and the length is ,16 + .14 which is .3. There you go!
