Divide by the coefficient of y.
y = (45/9)x
y = 5x
The constant of proportionality is 5.
Answer:
3,9,12
Step-by-step explanation:
The range is option A 3,9,12
Due to the fact that M, according to the original equation, must equal π/4, N would have to equal the same according the next one. Though, everything falls apart on cosM=tanN. Because cos(π/4)≠tan(<span>π/4). Though, everything works out for the rest.</span>
C= total $ cost
n= number of pizzas purchased
x= $ cost per pizza
C= x * n
C= xn
If you know the cost per pizza and the number of pizzas purchased, plug those numbers in the equation above to find the total cost.
EXAMPLE: If each pizza cost $10 and 5 were purchased, the equation would be: C= ($10)(5)= $50 total
ANSWER: C= xn
