How would I solve:
1/3(D+3)=5
I know you need to find the recipicile,
but I have no idea how to solve this.
1/3(D+3)=5
1/3D + 1 = 5
1/3D = 4
D = 4/(1/3)
D = 4 * (3/1)
D = 12
Where did the four come from?
To get the knowns on one side of the equation, I subtracted 1 from both sides.
To solve the equation 1/3(D+3) = 5, you need to follow these steps:
Step 1: Distribute the 1/3 to both terms inside the parentheses.
1/3(D+3) = 5 simplifies to (1/3) * D + (1/3) * 3 = 5
Step 2: Simplify the equation by multiplying.
(D/3) + 1 = 5
Step 3: Isolate the variable by subtracting 1 from both sides of the equation.
(D/3) = 5 - 1
(D/3) = 4
Step 4: To eliminate the fraction, multiply both sides of the equation by 3.
(3 * (D/3)) = (4 * 3)
D = 12
So, the solution to the equation is D = 12.
Note that the term "reciprocal" is typically used when you have an equation with fractions that need to be solved by cross-multiplication. In this case, you didn't need to find the reciprocal.
