Answer:
5050
Step-by-step explanation:
Answer : x = 20
Explanation :
3x + 2x +20 + 4x - 20 = 180
(3+2+4=9)
9x + 20 - 20
The 20s cancel each other out because one is positive and the other is negative
9x = 180
9x/9 = 180/9
X = 180 divided by 9
X = 20
The given equation is:
We have to find, which of the given set of parametric equations given in the options, result in the above equation:
The correct answer would be option A.
The equations in option A are:
From first equation we can see that 5t is equal to x. Using the value of 5th in second equation, we get the equation as:
Therefore, the correct answer is option A
