The required value of x is 36
Step-by-step explanation :
Let the required number be x.
Three fourth of number = (3/4)x
One third of number = (1/3) x
According to the question ;
3x/4 = x/3 + 15
→ 3x/4-x/3 = 15
→ 9x - 4x / 12 = 15
→ 5x = 15 x 12
⇒ x = 180 / 5
⇒ x = 36

Answer:
8
Step-by-step explanation:
we have
![6t-20-32u](https://tex.z-dn.net/?f=6t-20-32u)
Evaluate the expression for
t=6 and u=1/4
Substitute the value of t and the value of u in the expression above
![6(6)-20-32(1/4)](https://tex.z-dn.net/?f=6%286%29-20-32%281%2F4%29)
![36-20-8](https://tex.z-dn.net/?f=36-20-8)

Answer:
5 = n one solution, 11 = 11 is an infinite number of solutions, while 2 = 8 is no solution.
Step-by-step explanation:
Answer:
Greg worked more than 20 hours.
Step-by-step explanation:
Let's solve the inequality for
so we know how many hours Greg worked:
Step 1. Subtract 25 from both sides of the inequality
![14h+25>305](https://tex.z-dn.net/?f=14h%2B25%3E305)
![14h+25-25>305-25](https://tex.z-dn.net/?f=14h%2B25-25%3E305-25)
![14h>280](https://tex.z-dn.net/?f=14h%3E280)
Step 2. Divide both sides by 14
![\frac{14h}{14} >\frac{280}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B14h%7D%7B14%7D%20%3E%5Cfrac%7B280%7D%7B14%7D)
![h>20](https://tex.z-dn.net/?f=h%3E20)
We can conclude that Greg worked more than 20 hours.
