Answer:
<em>Addison worked 5 hours</em>
Step-by-step explanation:
<u>Proportions
</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
The relationship between the number of kilograms of dough Addison prepares (y) is proportional to the number of hours he works on it (x).
Knowing he prepared y=30 kilograms of dough after t=3 hours, we substitute in the function:
30 = 3k
Solving for k:
k = 30/3 = 10
The relationship is:
y = 10x
If he prepared y=50 kg of dough, then:
50 = 10x
Solving for x
x = 50/10 = 5
Addison worked 5 hours
46.2. 15.4 is one third of 46.2, therefore when you multiply it ny three, you get 46.2. All the problem is, is multiplying the input by 3.
Where’s the graph? I need it to answer the question
1 Answer. (5x)2−(10)2=(5x+10)(5x−10) , is the factorised form, hope that helps:)
