Answer:
Her daughters age: 1/2x
Step-by-step explanation:
Let's say Rani's present age is x. Her age is twice the age of her daughter.
So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.
1/2(20)=daughter's age
so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.
hope this helped :-) <3
Step-by-step explanation:
mean is always equal to additon of total no.s by total no.s
2 + 4 + 6 + 8 + 10 + 12
=42
total no.s = 6 no.s
42/6
=7
therefore 7 is the answer which is the mean deviation of the following no.s .
The value of x is -3, or x= -3
Answer:
{M, i, s, p}
Step-by-step explanation:
The elements of the set are the letters in Mississippi. But remember, elements cannot repeat themselves! So the elements of this set would be {M, i, s, p} since all the other letters are just repetitions.
Hope this helps!!
Answer:
The equation is 
Step-by-step explanation:
The parameter that we have is t. We want to eliminate this parameter in both equations, therefore in the first equation we solve for t and in the second equation we solve for the variable t.
We have:
Now we solve the other equation for t.
<em> because</em> 
As 
and also 
Then:
