I’m pretty sure this is right:
The other number is -3.
Step-by-step explanation:
Step 1; First we develop formulae for the given information. A number is added with 3 and the resulting sum is multiplied by 4. This number is then divided by 2 and the quotient is 0. Assume the unknown number is x, then the given information is as follows
The quotient of
is 0. So
= 0.
Step 2; Now we solve the above equation. The denominator is taken to the RHS and the RHS remains zero.
= 0, 4(x+3)= 0, 4x+ 12 = 0, 4x = -12, x =
= -3.
So the other number is -3.
This would be 2(6)^4 + 5*6
= 2592 + 30
= 2622 Answer
Answer:
x=1+√5 or x=1−√5
Step-by-step explanation:
$78.17 rounds to $78
15% of $78 = $11.70 which rounds to $12
