Answer:
The width is: 
The length is 
Step-by-step explanation:
The given rectangle has area given algebraically by the function:
The width of the rectangle is the greatest common factor of 
, 
and 
That is the width is:
We now divide the area by the width to obtain the length of the rectangle:
This simplifies to:
Answer:
<u>£4.20</u>
Step-by-step explanation:
Let :
- cost of 1 kg banana = x
- cost of 1 kg apple = y
Equations formed :
- 4x + 3y = 7.50 [Equation 1]
- 3x + 5y = 8.10 [Equation 2]
Multiply Equation 1 by 5 and Equation 2 by 3 :
- 20x + 15y = 37.50
- 9x + 15y = 24.30
Subtract the newly formed equations :
- 11x = 13.20
- <u>x = 1.20</u>
Finding y :
- 4(1.20) + 3y = 7.50
- 4.80 + 3y = 7.50
- 3y = 2.70
- <u>y = 0.90</u>
Then :
- Cost of 1 kg banana = £1.20
- Cost of 1 kg apple = £0.90
Cost of 2 kg bananas and 2 kg of apples :
- 2(1.20) + 2(0.90)
- 2(2.10)
- <u>£4.20</u>
The first quiz (4/5 with 15 questions)
on that quiz, Kelly got 12/15 questions correct and the other quiz, she only got 10/12. since 12 is a higher number than 10 it means the answer is the first quiz.
