Ritz can eat 8 apples in 15 minutes.how long does it take ritz to eat 16 apples at the same rate.

zhannawk [14.2K]

We can answer the problem using a rule of three, simple, direct proportion and also using fractions. First the rule of three:
8 apples ------> 15 min
16 apples ----> x

x = (16)(15)/8
x = 30
therefore he can eat 16 apples in 39 minutes.

We can also equate fractions like so:
8/15 = 16/y
and solve for y:
y = 15*16/8
y = 30
the same answer

What is the slope of the line that passes through the points (-3, -3)(−3,−3) and (-18, -23) ?(−18,−23)? Write your answer in the

Kryger [21]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the slope of linear functions using two points, we have the following equation :

$slope = \frac{y(b) - y(a)}{ x(b) - x(a) } \\$

Where a and b are two point of the function.

_________________________________

Step (2)

Well now I want to choose a name for the given points :

a = ( -3 , -3 ) ••••••••• b = ( -18 , -23 )

_________________________________

Step (3)

It's time to put the the coordinates in the above equation :

$slope = \frac{ - 23 - ( - 3)}{ - 18 - ( - 3)} \\$

$slope = \frac{ - 23 + 3}{ - 18 + 3 } \\$

$slope = \frac{ - 20}{ - 15} \\$

Negatives simplified :

$slope = \frac{20}{15} \\$

The face and denominator are reduced to five :

$slope = \frac{4}{3} \\$

And we're done.

Thanks for watching buddy good luck.
