Answer:
False
Step-by-step explanation:
It is given that Noah thinks :
9x - 2x + 4x = 3x as the subtraction sign after 9x tells us to subtract everything that comes after 9x.
This is wrong as according to the BODMAS rule, we have to do the addition operation first and then followed by subtraction operation.
That is
⇒ 9x - 2x + 4x
⇒ (9x -2x)+ 4x
⇒ 7x + 4x
⇒ 11x
Therefore the answer to the equation is 11x and not 3x.
Well, if 10 people are heading to the park and each car holds 5 people, we can write the equation, "5x = 10" so, we need to get x by itself. To do that we need to get rid of the five. Whatever we do to one side, we do to the other. So 5/10 = 2 so, 2 cars are needed. Hope that helps! :)
