P = a + b + c =4.81 + 8.8 + 8.42 = 22.03
Answer:
The number is -32
Step-by-step explanation:
Let the number be x, then 11 minus the quotient of a number and 8 is 15 becomes:
![11 - \frac{x}{8} = 15](https://tex.z-dn.net/?f=11%20-%20%20%5Cfrac%7Bx%7D%7B8%7D%20%20%3D%2015)
We group similar terms to get:
![- \frac{x}{8} = 15 - 11](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7Bx%7D%7B8%7D%20%20%3D%2015%20-%2011)
![- \frac{x}{8} = 4](https://tex.z-dn.net/?f=-%20%20%5Cfrac%7Bx%7D%7B8%7D%20%20%3D%204)
Multiply both sides by -8 to get:
![x = 4 \times - 8](https://tex.z-dn.net/?f=x%20%3D%204%20%5Ctimes%20%20-%208)
Simplify to get:
![x = - 32](https://tex.z-dn.net/?f=x%20%3D%20%20-%2032)
Answer:
w=-11/4 or -2 and 3/4
Step-by-step explanation:
To solve this, we first have to cancel out the dividing by-3. We can use the inverse operation of division, which is multiplication. We have to multiply both sides by -3, and the equation becomes 4w+5= -6. Then, we subtract 5 from both sides. We get 4w= -11. We finally divide 4 on both sides, getting w=-11/4. -11/4 is in improper fraction form and -2 and 3/4 is in mixed number form.
