Buying apples and bananas with $10
5 pounds of bananas so
5 x .80 = $4
5 pounds of apples so
5 x 1.40 = $7
$7 + $4 = $11
she only has $10
$11 - $10 = - 1,00
so no. she will not recieve any change because she doesnt havew enough money
The roof is made up of 2 similar pieces of 2 rectangle shapes.
----------------------------------------------------------------
Area of a rectangle = Length x Width
----------------------------------------------------------------
Area of a rectangle = 50 x 14 = 700 ft²
----------------------------------------------------------------
Area of 2 rectangle pieces:
----------------------------------------------------------------
Area of 2 rectangle pieces = 700 x 2 = 1400 ft²
----------------------------------------------------------------
Find the cost:
----------------------------------------------------------------
1ft² = $2.75
1400 ft² = 2.75 x 1400
1400 ft² = $3850
---------------------------------------------------------------------------------------------
Answer: It will cost $3850 to have the roof replaced. (Answer A)

Graph A.....parallel lines will have no solution because they never intersect
First of all, you can simplify the 4 at the numerator and the 14 at the denominator (they're both multiple of 2):

Now, rationalize a denominator means that you have to get rid of the square root, in order to have an integer denominator.
To do so, remember that you can always multiply any number by 1 without changing its value, and you can always think of 1 as a fraction where numerator and denominator are equal:
