Answer:
17.5
Step-by-step explanation:
Given that the variables x and y have a proportional relationship.
i.e. y is directly proportional to x or can be written as
y = mx where m is the constant of proportionality.
When x =2, y =7
Substitute this to get the value of m.
7 =2m or m = 3.5
Thus the relationship between x and y is
y = 3.5x
So when x=5, y = 3.5(5) = 17.5
Answer:
14q^2−2q+14/3
Step-by-step explanation:
9q^2 - 2/3 (3q - 7) + 5q^2
Use the distributive property to multiply -2/3 by 3q−7.
9q^2 - 2q + 14/3 + 5q^2
Combine 9q^2 and 5q^2 to get 14q^2
14q^2−2q+14/3
Y is the independent variables
k is the dependent variable
Step-by-step explanation:
so, you don't know what a division is for ?
it is to ask things like "how often does one number fit into another number", or "how big will each piece be, if I split something into a certain number of equally sized pieces ?".
this is what we need here.
8 pizzas for $131.36. and each pizza costs the same. you see how that connects to what I just described above ?
to find how much each pizza cost, we need to divide the total price by 8, to find the size (= here the price) of each of the equally big parts of the total price.
131.36 / 8 = $16.42
