100 posts have to be placed

Just find the perimeter, then divide by distance between posts.
(270x2)+(330x2)=1200
1200/6=200

Mike has 21 pounds of tomatoes and 9 pounds of mixed peppers from his garden that he will use to make sals.

Grace [21]

The number of batches of salsa that can be made = x = 6 batches

The number of bat tomato sauce that can be made = y = 3 batches

Step-by-step explanation:

We are given the system of equations:

$x+5y=21\\x+y=9$

where variable x represents the number of batches of salsa that can be made and y represents the number of bat tomato sauce that can be made.

We need to solve the systems to find the values of x and y.

Let:

$x+5y=21\,\,\,eq(1)\\x+y=9\,\,\,eq(2)$

Subtract both equations:

$x+5y=21\\x+y=9\\-\,\,\,-\,\,\,\,\,\,-\\------\\4y=12\\y=\frac{12}{4}\\y=3$

So, value of y=3

Putting value of y in eq(2) and finding value of x:

$x+y=9\\x+3=9\\x=9-3\\x=6$

So, value of x=6

The number of batches of salsa that can be made = x = 6 batches

The number of bat tomato sauce that can be made = y = 3 batches

Help how do I do this!!!!

In order to find each one, we need to divide 23.96/4 to find what each pound costs. After dividing, you get 5.99. Each pound costs 5.99. So for the first one just multiply 2x5.99 and get 11.98. And the second one shows 17.97 so we can just divide 17.97 by 5.99 and get 3. Just work off of that and you’ll get the rest! But the answer would turn out to be C because you add 5.99 to 23.96 and you get 29.95! Hope this helped
