7 because there will be some cans left at the 6 hours and 7 all will be gone.

You take the total amount of cans (80) and divide it by the total amount of cans per hour so you would do 80/12
And that equals 6.666 or 6 2/3

melomori [17]

Answer:

Chantal and Trisha will have both traveled 105 miles in 20 minutes.

Step-by-step explanation:

$y$ is distance in miles, $x$ is time in hours.

The two equations are:

$y = \frac{20}{x} + 45$

$y = \frac{35}{x}$

Set them equal to each other and solve for x:

$\frac{35}{x} = \frac{20}{x} + 45$

$\frac{35}{x} - \frac{20}{x} = 45$

$\frac{35-20}{x} = 45$

$\frac{15}{x} = 45$

$x = \frac{15}{45} = \frac{1}{3} hours = 20 minutes$

Plug that back into the equations to confirm this $x$ gives the same $y$ :

$y = \frac{20}{1/3} + 45 = 105 miles$

$y = \frac{35}{1/3} = 105 miles$

Write the answer in standard form.

viktelen [127]

Answer and step-by-step explanation:

We learn that (a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3

So in this case, it would be:

= x^3 + (3*x^2*2) + (3*x*2^2) + 2^3

= x^3 + 6x^2 + 3x * 4 + 8

= x^3 + 6x^2 + 12x + 8

This is the standard form of the equation

Hope it help you :3
