It takes 250 g of pasta and 240 ml of sauce to make one batch of spaghetti and it takes 600g of pasta and 700ml of sauce to make one batch of lasagna.
Case 1: Pasta
The chef wants to make spaghetti and lasagna using more than 4000 g of pasta.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes :

Case 2: Sauce
chef wants to make spaghetti and lasagna using more than 5000 ml of sauce.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes:
Answer :
The two equations are :
For pasta: 
For sauce:
Answer:

Step-by-step explanation:
Answer:
a) enlargement
b) scale factor is 2
Step-by-step explanation:
As we can see, we went from the block to the red figure
a) Since the red figure is bigger, then what we have is an enlargement of the original figure
b) As we can see, the coordinates of the red is two times the value of the coordinates of the black
So, we can conclude that what we have as a scale factor is 2
Answer:
Average growth= 11.20 feet
Step-by-step explanation:
<u>First, we need to calculate the total growth during those 312 years:</u>
<u></u>
Total growth= 3,512 - 18
Total growth= 3,494 feet
<u>Now, the average growth:</u>
<u>Average growth= total growth / number of years</u>
Average growth= 3,494 / 312
Average growth= 11.20 feet
