Answer:
Step-by-step explanation:
we are given that these two fractions are equal. however, 20/r is just given in numerators and denominators that are four times as large, even though it is still equal to 5/7. we can tell this because 20 is 4 times larger than 5, which means that R must be 4 times larger than 7, right? YES. so we take 7*4 to get 28.
Hey.. don’t click on that link or any links on here !!! but i jus wanna say you didn’t attach an image of your question :).
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>

$4500
Step-by-step explanation:
$350 x 10 = 3500 + 1000 which ends up with a total of $4500. I hope this helped :)
