The average price is calculated by dividing the sum of all prices with the number of items.
average price= price1+price2+...priceN/N
In our case , we have four pairs of shoes.So, N=4.
We also know the average price. average price=$50
We also know the price of the first pair of shoes (price1), of the second (price2) and the third (price3). We need to find out Price4:
$50=$35+$40+$55+Price4/4
50*4=<span>$35+$40+$55+Price4
$200=$130+Price4
Price4=200-130
Price4=$70</span>
Answer:
The expression 5(4x - 7) + 3(3x + 3) can be simplified to 29x - 26
Step-by-step explanation:
The first step in solving this is to apply coefficients to the contents of the brackets:
5(4x - 7) + 3(3x + 3)
= 5 × 4x - 5 × 7 + 3 × 3x + 3 × 3
= 20x - 35 + 9x + 9
Now you can group like terms:
20x - 35 + 9x + 9
= 20x + 9x - 35 + 9
= (20 + 9)x - 26
= 29x - 26
And that is the final answer.
Area of the triangle = (1/2)(base)(height) = (1/2)(4)(5) = 10 square units.
The correct answer is A.
√20 = 4.47213
√20 = 4 (nearest integer)
√20 = 4.5 (nearest tenth)
