MissTica

Answer: The number of batches made by Vanessa last weekend = 5

Number of batches made this weekend =20

Step-by-step explanation:

Let x be the number of batches made y Vanessa last weekend.

Given : This weekend Vanessa made 4 times as many batches as last weekend.

i.e. Number of batches made this weekend = 4x

She made a total of 25 batches for the two weekends.

i.e. $x+4x=25$

$\Rightarrow\ 5x=25$

Divide both sides by 5 , we get

$x=5$

i.e. number of batches made y Vanessa last weekend = 5

Number of batches made this weekend =20

Hence, the number of batches made by Vanessa last weekend = 5

Number of batches made this weekend =20

Answer:

k = 45 . . . miles per hour
k = 1/45 . . . hours per mile

Step-by-step explanation:

One way we can relate distance and time is ...

time = k × distance

Then the value of k (the constant of proportionality) is ...

k = time/distance = 4 hours/(180 miles)

k = (1/45) hours/mile

Another way we can relate the variables is ...

distance = k × time

Then the value of k (the constant of proportionality) is ...

k = distance/time = (180 miles)/(4 hours)

k = 45 miles/hour
