Let's call the short side "s"
short side = "s"
middle side = 3s
longest side = 2*3*s
perimeter = 45 cm
perimeter = s + 3s + 6s = 45
short side = 4.5
middle = 13.5
long side = 27
4.5 + 13.5 + 27 = 45
3 3/5 + v + 5 2/3 = 15
18/5 + v + 17/3 = 15
54/15 + v + 85/15 = 225/15
v = 225/15 - 139/15
v = 86,/15 = 5 11/15, answer B
Answer:
Amanda > Todd > Derrick
Step-by-step explanation:
Amanda's IQR- 3.5
Derrick's IQR- 2
Todd's IQR- 3
Answer:
475
Step-by-step explanation:
Let's call the dryer price is x
Then, the price for the washer is 53 more than the dryer, it would be: x+53
Total price of washer and dryer = 1003
We get the equation:
x+(x+53) = 1003
2x + 53 = 1003
2x + 53 - 53 = 1003 - 53
2x = 950
x = 475
The dryer price is 475
Extra: you can find the cost of the washer by using x+53 = 475+53 = 528
