If the original price is 'x', 60% of 'x' is $30
0.6*x = 30
30/0.6 = x
x = 50
The original price is $50
Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding decrease in the other variable. Also, a decrease in the value of one variable would cause a corresponding increase in the other variable.
The time, t, required to drive a fixed distance varies inversely as the speed, r. By introducing a constant of variation, k(the fixed distance), the expression becomes
t = k/r
It takes 8 hr at a speed of 15 km/h to drive a fixed distance. It means that
8 = k/15
k = 8 × 15 = 120
The equation becomes
t = 120/r
Therefore, the time it will take to drive the same distance at a speed of 29 km/h is
t = 120/29 hours
Converting to minutes, it becomes
120/29 × 60
= 248. 28 minutes
248 minutes, 28 seconds
3 is the remainder because the closest is 7 times 21 so it’s remainder 3
6 lbs 2 oz. 6 lbs = ?oz
6×16 =96oz+2 oz =98oz David's weight
5lbs 5oz 5lbs=?oz
5×16=80oz+5oz=85oz Daniel's weight
98oz+85oz=183oz (c)
