Since the
density =mass /volume
if volume is constant we can rewrite the density equation as
volume=mass / density
since volume is just a constant
c*density=mass
where c is some constant that denotes the constant volume
mass and density will be proportional to each other or in other words will be have exactly in the same way if one increase the other will increase if one decreases the other will decrease if one stays constant the other will stay constant
only the fourth choice satisfies the proportionality condition so it must be the correct choice
Answer:

Step-by-step explanation:
To solve the problem, you must expand the trigonometric expression using the information given.

Answer:
Cost of raisin per ounce = $0.8
Step-by-step explanation:
Solution:
Number of ounces = 5 ounces
Price of 5 ounces= $4
Cost of raisin per ounce = ?
To find out the price per ounce, simply take the total dollar amount of the product and divide it by the number of ounces.
Formula = Price/Number of ounces
= 4/5
=$0.8
Cost of raisin per ounce = $0.8....
Since it is an expression and not an equation, you would just have to distribute the -3 to the two inside the parentheses.
The answer is -9 + 30x
