Answer:
4D - 1
Step-by-step explanation:
So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.
Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.
Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.
The fraction is in simplest form when the GCF of the numerator and denominator is 1.
For example, 1/2 is in simplest forms, but 2/4 isn't
Missing sign in the first equation.
I think it should read:
y=4x-6
y=2x
