It will take Tom 80 minutes to clean all 4 gardens. Or, 1 hour and 20 minutes.
1(6x-9)=(4x-6)
One solution was found :
x = 3/2 = 1.500
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
1*(6*x-9)-((4*x-6))=0
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
6x - 9 = 3 • (2x - 3)
Equation at the end of step 2 :
3 • (2x - 3) - (4x - 6) = 0
Step 3 :
Equation at the end of step 3 :
2x - 3 = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : 2x-3 = 0
Add 3 to both sides of the equation :
2x = 3
Divide both sides of the equation by 2:
x = 3/2 = 1.500
One solution was found :
x = 3/2 = 1.500

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>
