Answer:
46
Step-by-step explanation:
let the number added by this be X ,X+15 = 61 then solve
(5x-3) - 7(x-2) = 2(4x+3) - 3(2x-4) + 1
5x - 3 - 7x + 2 = 8x + 6 - 6x + 4 + 1
-2x -1 = 2x + 11
-4x = 12
<em>x = -3</em>

Answer:
Substitute 6 for x in the equation
Step-by-step explanation:
The equation is looking for what x equals so if 6 is the solution to the equation it would represent x.
The probability of an event being very likely means that it has a high chance of occurring, or the probability is close to 1. Remember that with probability, it goes from 0 to 1 only. There are no negatives, and it is all decimals.
Therefore, the correct answer is C. 0.89. This is because there is almost a 90% chance of the event occurring, as the probability is 0.89.
