Answer:
15 years
Step-by-step explanation:
Let e represent Edith's age. Then e also represents her brother's age.
Then:
e = 5e - 60.
Consolidating the e terms, we get 60 = 4e. Thus, e = 15.
Edith is 15 years old. So is her brother.
Answer:
g(x)
because it is a quadratic equation it is mirrored the other one isn’t even a function
Answer:
11 km/hr.
Step-by-step explanation:
Given information:
Simulated speed = 20/km/h
Time = 15 mins = 1/4 hr = 0.25 hr
Distance Covered as per simulated speed =
Position of Julian according to the app = .
Actual distance covered by the bike is
Formula for speed:
Therefore, the average speed of Julian is 11 km/hr.
The value is 62.50
To the get whole value or 100 % of the value, we always divide the value to its corresponding percentage.
25 is the value; 40% is the percentage of 25 from the whole value.
25 / 40% = 62.50
In the event that the value of a part and the whole is given and the percentage is required. Simply divide the part by the whole to get its percentage of the whole.
whole = 62.50
part = 25
25 / 62.50 = 0.40 * 100% = 40%
If the whole value and the percentage is given. To find the value of the percentage, simply multiply the whole to the percentage.
whole = 62.50
percentage = 40%
62.50 * 40% = 25
He Is not correct because they are all equivalent to each other if u simplify it .5=.5=.5 five is in the same spot every time
