Answer:
<em>5</em>
Step-by-step explanation:
General equation of direct variation:
y = kx,
where k is the constant of proportionality.
In your case, you have
y = 5x, so 5 is the constant of proportionality.
Well, if y is the notebook cost, well x+y=6.28, x+x+0.70=6.28, 2x=5.58, x=2.79.
The pencil box costs $2.79, while the notebook costs $3.49.
Answer:
{42,56,70}
Step-by-step explanation:
a^2 + b^2 = c^2
42^2 = 1764
56^2 = 3136
70^2 = 4900
3136 + 1734 = 4900
Answer is D
sum of constants = 8 + 4 = 12
sum of coefficients = 7 + 3 = 10
12 > 10
