Solve for a
3b=10b-49
Solve for b
Answer:
The first answer is a = 10, The second answer is b = 7
Step-by-step explanation:
Equation 1: 5a = a + 40
To solve for a, you want to isolate a on one side of the equation. You can do this by subtracting "a" from both sides of the equation:
5a - a = a - a + 40
This simplifies to:
4a = 40
Now, divide both sides by 4 to solve for a:
4a/4 = 40/4
a = 10
So, a = 10.
Equation 2: 3b = 10b - 49
To solve for b, you want to isolate b on one side of the equation. First, let's get the "b" terms on one side by subtracting 10b from both sides:
3b - 10b = 10b - 10b - 49
This simplifies to:
-7b = -49
Now, divide both sides by -7 to solve for b:
(-7b) / (-7) = (-49) / (-7)
b = 7
So, b = 7.
The amount of paint shared by each teacher is 0.75 gallons
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that four teachers share 3 gallons of paint equally. The amount of paint shared by each teacher is calculated by dividing the quantity of paint by the number of teachers.,
Amount of paint = 3 / 4
Amount of paint = 0.75 gallons
