A square by definition has sides of equal length - and the area of a rectangle is calculated by multiplying the length of the two sides together.

Taking the value of one side of the square to be x, we know that the area of the square is x^2.

Therefore to find x, we need to take the square root of 2500, which is 50.

At Grocery Mart, tomatoes are $2.75 per pound, or you can buy a 5
larisa [96]

Answer:

a) $2.75

b) $2.2

c) Second tomato option is better value option.

Step-by-step explanation:

First option to buy tomatoes = $2.75 per pound

Second option to buy tomatoes:

To buy a box which is a 5 pound box and the price is $11.

To find:

a) Unit price for the first tomato option.

b) Unit price for the second tomato option.

c) Better value option on the basis of price.

Solution:

Let the consider the unit here to be a pound.

So, we will find the price of tomato per pound to find the unit price of tomato.

a) Unit price of the first tomato option is : $2.75 per pound

b) Unit price of the second tomato option:

Price for 5 pounds = $11

Dividing both sides with 5 to find the price of 1 pound or unit price.

Price for \frac{5}{5} = 1 pound = \frac{\$11}5  = \$2.2

c) To find the better value option, we can compare the unit prices of the two tomato options.

Here, we have the two tomato options with unit prices as:

$2.75 and $2.2

Second tomato option has a lower unit price, therefore, <em>second option</em> is better value option on the basis of price.

9x + 26 + 7x - 17 = 2x + (-3x) + 5x
slega [8]
9x + 26 + 7x - 17 = 2x + (-3x) + 5x =
16x + 9 = 2x - 3x + 5x =
16x + 9 = 4x
9 = 4x - 16x
9 = - 12x
-9/12 = x
- 3/4 = x
