The distance would be, ((x1-x2)^2+(y1-y2)^2)^0.5
x1=-7,y1=9, x2=-4,y2=2
hence distance = sqrt(9+49) = sqrt (58) = 7.615773106
Answer:
Step-by-step explanation:
65=0.20x
x=65/0.2
x=325 miles
It would be: 2 × x + 4 + 2× x
= 2x + 4 + 2x
= 4x + 4
In short, Your Final Answer is 4x+4
Hope this helps!
Let S = the original price of the sweater. Now, lets step through the problem...
The friend goes shopping with $35 and ends up left with $10.50. This means she spent 35 - 10.50 = 24.50 on the sweater after the sale and coupon.
Next, the sweater is on sale for 50%. This means we take S and take 50% of that. S*.50
Next, she uses a $5 off coupon. Thus, we want to subtract $5 from the price.
Lets combine this all together!
24.50 = S*.50 - 5
Solve for S.
24.50 = S*.50 - 5
29.50 = S*.50
$59 = S
Thus, the original price of the sweater was $59.
