First, you add like terms. In this case, the like terms are 6 and 3.
4x + 6 + 3 = 17
4x + 9 = 17
Then, subtract 9 on each side:
4x + 9 - 9 = 17 - 9
4x = 8
Then divide by 4 on each side to get the x by itself:
4x/4 = 8/4
x = 2
Answer:
Degree: 5
Leading Coefficient: -7
Step-by-step explanation:
Let Mary's age be x.
Paul is three times as old as Mary, so Paul's age would be 3x.
Peter is four times as old as Mary, so Peter's age would be 4x.
The sum of their ages is 64
⇒ Paul's age+ Peter's age+ Mary's age= 64
⇒ 3x+ 4x+ x= 64
⇒ 8x= 64
⇒ x= 64/8
⇒ x= 8
Paul's age is: 3x= 3*8= 24
Peter's age is: 4x= 4*8= 32
Final answer: Paul is 24 years old.
Peter is 32 years old.
Mary is 8 years old.

Answer:
2 feets
Step-by-step explanation:
Given that :
Alli's Initial depth = 6 feets
Number of feets in which Alli rose = 4 feets
Alli's new position relative to the surface of the pool:
Difference of Alli's initial depth and feets risen :
6 feets - 4 feets = 2 feets
Hence, Alli is now 2 feets below the surface of the pool.
Given:
Alan salary P (in dollars) when he works h hours is represented by the equation
