Step-by-step explanation:
50 / 0.40 = 125
To check your answer, 125 * 0.4 = 50
Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is 
then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.
Answer:
2.9 mi
Step-by-step explanation:
The time difference t between 12.30pm and 3.30pm is 3h.
Let the distance to Marat's house be s.
The equation to calculate velocity v is given by:
v = distance / time.
Now you can write an equation for the time difference t and use the two velocities and the 90 min(= 1.5h) she stays:
3 = s/12 + 1.5 + s/2.3
Solve this equation for s:
(1/12 + 10/23)* s = 1.5
s = 2.9
