Answer:
The answer is zero there is no solving.
Step-by-step explanation:
cause you do
60/n=20/7, and then you move all the terms to the left
now it is: 60/2-(20/7)=0
the domain to this is n=0
add the numbers and variables together and get
60/n-(+20/7)=0 now get rid of the parentheses and now you got
60/n-20/7=0
and all that is 0
kinda hope this help lol

Answer:
17n+9 feet
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(L +W)
P = 2((4.5n +9) +(4n -4.5)) = 2(8.5n +4.5)
P = 17n +9
The perimeter of the rectangle is 17n +9 feet.
Answer:
<u>There are 97 nickels in the jar</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of coins = 205
Number of nickels = x
Number of quarters = 205 - x
Value of the 205 coins = $ 31.85
2. If both of these statements are true, how many nickels are in the jar?
Let's solve for x, this way:
0.05x + 0.25 (205 - x) = 31.85
0.05x + 51.25 - 0.25x = 31.85
-0.2x = 31.85 - 51.25
-0.2x = - 19.4
x = -19.4/-0.2
x = 97 ⇒ 205 - x = 108
<u>There are 97 nickels and 108 quarters in the jar</u>
The given equation of sphere is
We have to use completing the square method , and in that method, we have to divide 12x ,-4y,2z by 2, square the results, and add the reult obtained after squaring to both sides. That is
So here the center is (-6,2,-1) and radius is 2 .
I) 4 Gallons
II) $77
Step-by-step explanation:
30km 1 gallon
420km ?
420 ÷ 30 = 14
? = 40
So, 4 gallons more will be needed to complete the journey.
1 gallon $5.50
14 gallon $?
14 x $5.50 = $77
The cost of the petrol is $77
