Answer:
Step-by-step explanation:
Ok, let's do this step by step....
Let's first simplify the x's:
Then we breakdown the 54 as 2 * 27 then simplify with the 10 above.
Now, we can rewrite this as the following and solve the bottom part:
The solution is
Answer:
6mph
Step-by-step explanation:
In this question, we are asked to calculate the speed at which Carol jogs, given that she has a particular speed when she jogs greater than when she walks.
Firstly, we should understand that she is taking the same distance, whether she jogs or walks.
Now, let’s say her jogging rate is x mph, this means that her walking rate would be (x - 4)mph. This is because her jogging rate is 4mph faster than her walking rate.
The total distance covered when jogging is thus 10/60 * x, while her total distance covered when walking would be 30/60 * (x-4)[we convert the time to hours]
We equate both since they are same distance:
x/6 = (x -4)/2
2x = 6(x - 4)
2x = 6x - 24
4x = 24
x = 6mph
Answer:
x < 8
Step-by-step explanation:
Add 4 to both sides
5x=40
Divide by 4
x < 8
Since it is depreciation, the equation would be
500(0.7)^5
500 being starting price, 0.7 being price after 30% is taken off, and 5 being number of years
the worth would be $84.04 in five years
Answer:
150
Step-by-step explanation:
because it is literally a "tenth"
also you could have solved this in a second .-.
