What is the solution to this equation x 5 equals 30?
6
The number 64 is the next logical number in the following sequence of numbers 2 6 14 30?
No, it would be 62. The equation is: f(n) = 2(f(n - 1) + 1), with f(0) = 0. So f(5) = 2(30 + 1) = 62
What integer divided by the sum of negative 4 and positive 6 equals negative 15?
Set up an equation using x for the integer. The equation would be: x/(-4+6)=-15 Firstly find the sum of -4 and 6. It would be 2. The equation is now: x/2=-15 Multiply both sides by 2. This means that: x=-30 Plug it back into the equation to check: -30/(-4+6)=-15 -30/2=-15 -15=-15 It works therefore -30 is the integer that when divided by the sum of negative 4 and positive 6 equals negative 15.
I am a number Divide me by 6 Add 25 to the result You will get me What number am i?
Call the number n. From the problem statement, (n/6) + 25 = n. Multiplying both sides by 6 yields n + 150 = 6n, or 150 = 5 n or n = 30.
What is 6 more than a number equals two times the sum of one-half the number plus three?
Oh, dude, this is like some math riddle from a bad dream. So, if we break it down, it's saying 6 more than a number is equal to 2 times the sum of half the number plus three. So, the number is 9. Math can be fun... sometimes.
