Angelo grows vegetables and sells them at a farmers'
irina [24]

Answer:

$7.55

Step-by-step explanation:

We can solve this by using a system of equations. The equations would be set up like this:

2c + p = 3.15\\3c + 2p = 5.35\\

Let's isolate a variable in the first equation:

p = -2c + 3.15

Now we can plug this in to the second equation:

3c + 2(-2c + 3.15) = 5.35\\3c - 4c + 6.3 = 5.35\\-c + 6.3 = 5.35 \\-c = -.95\\c = .95

Now that we have found c we can find p by plugging c in to an equation

2(.95) + p = 3.15\\1.9 + p = 3.15\\p = 1.25

We have found both variables now we can use the following equation to answer the question:

4c + 3p = ?\\4(.95) + 3(1.25) = ?\\3.8+3.75 = 7.55

Therefore, the price in dollars of 4 cucumbers and 3 peppers is $7.55.

x + x + 2  = 3(x + 2) - 2x

2x + 2 = 3x + 6 - 2x

2x + 2 = x + 6

x = 4

The numbers are 4 and 6.

Step-by-step explanation:

7x^2 -28

Factor out a 7

7(x^2 -4)

The terms inside the parentheses is the difference of squares, so it is factorable  (a^2-b^2) = (a-b)(a+b)
