Question
4T - 8D = 12H
The given equation can be rewritten as
T = aD + bH , where a and b are constants. What is the value of a?
The correct answer is: 2
HINT: Rewrite the given equation and then compare the coefficients.
Complete step by step solution:
Given equation is 4T - 8D = 12H
Add 8D on both sides,
We get, 4T = 12H + 8D
Divide each term on both the sides by 4,
T = 3H + 2D
That is, T = 2D + 3H
While comparing T = 2D + 3H with T=aD + bH , we get a = 2 and b = 3
So, the value of a is 2.
A constant is a fixed value that does not change. Symbols such as a, b, c, etc., often represent constants. These constant symbols are used in algebraic expressions and equations to represent fixed values that do not change as per the above question; a and b are constants.
