Let's solve for x the following question:
3/4 (x - 16) = 5/4 (2x - 32)
As I told you on the previous exercise:
Step 1: Solve the parenthesis
3/4 x - 48/4 = 10/4 x - 160/4
Step 2: Like terms
3/4x - 10/4x = -160/4 + 48/4
-7/4x = -112/4
Step 3: Simplifying
-7/4x = -28
Step 4: Multiplying by 4 at both sides:
-7/4x * 4 = -28 * 4
-7x = -112
-7x/-7 = -112/-7
x = 16
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!
