35+5t=amount in tank A after t minutes
100-8t=amount in tank B after t minutes
same amount
35+5t=100-8t
add 8t both sides
35+13t=100
minus 35 both sides
13t=65
divide by 13 both sides
t=5
5 minutes
Answer: 3 1/2
Step-by-step explanation:
Change to common denominator of 6.
2 1/3 = 2 2/6. (Multiply fraction by 3/3 to get 2/6)
Now you can add.
2 2/6
+ 1 1/6
—————
3 3/6
3/6 can be simplified to 1/2 by dividing numerator and denominator by 6.
answer = 3 1/2
Answer:
x=3
Step-by-step explanation:
the volume of the prism with triangular base is 54 unit³
The base is a triangle with, base i.e 4 units and height i.e x units
Also, height of the prism = 3x
So, volume of the prism is,
And
,
Then,
As the volume is given as 54 unit³, hence
6x²=54
x²=9
x=3
The method of successive differences uses subtraction to the one number to the next and the process goes on until the difference settles constant which is not equal to zero. In this case, the constant difference reaches 25. Reversing the process to get the next term, the answer is 2509.
Use the triangle angle theorem:
All interior angles of a triangle equal 180 degrees.
If you use the theorem you should get the first one 19,70,91
