Let the number be x.
Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3
So, combining these into an equation, we get:
3x + 6 - x - x = x + 3
If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3
Therefore, this is a false statement.
Answer: He had $80 after selling those peaches.
----------------------------------------------
He had $60 worth of peaches.
He sold each one for $4.
Add a 4 to each peach that he has.
Or just do 4x20=$80.
Hey there!!
Hmmm you seem familiar :D
Okay let's get started!!!! Okay so remember that if two lines are parallel then the slopes must be exactly the same (ex: -4 and -4) if two lines are perpendicular then the slopes are negative reciprocals (ex: -4 and 1/4)
y = -3x + 7 -2x + 6y = 3
y = (x/3) + 1/2
So these two are perpendicular since the slopes negative reciprocals
y = (x/5) + 6 -2x + 10y = 5
y = (x/5) + 1/2
So these lines are parallel since the slopes are exactly equal
I hope this helps!

Answer:
C.) y = 5/4 x
Step-by-step explanation:
5/4 multiplied by 0.4 is 0.5
Answer:
The probability that the ball drawn from the second box is red is 40/99
Step-by-step explanation:
We can divide the event that the second ball drawn is red into 2 disjoint events, and obtain its probability by summing both probabilities for the disjoint cases.
- Case 1: The ball drawn from the first box is red and the ball drawn for the second box is also red
- Case 2: The ball drawn from the first box is green but the ball drawn from the second box is red
For the first case, we have 11 balls in the first box, 7 of them being red. Thus, the probability of drawing a red ball is 7/11. After that, we will put the red ball drawn in the second box, so that it will have 9 balls in total, 4 of them being red. As a consecuence, the probability of drawing a red ball in this instance is 4/9. We need to multiply that probability by the probability that a red ball was drawn first, so we have a probability of 7/11 * 4/9 = 28/99 that the balls drawn are both red.
Now, lets go to the second case. The probability of drawing a green ball from the first box is 4/11, and after placing that ball in the second box, the probability that the new ball drawn is red is 3/9 = 1/3; this is because we will have 3 red balls out of a total of 9 (6 are green). Thus, the probability of this second event is 4/11 * 1/3 = 4/33.
Combining both probabilities, the probability that the ball drawn in the second box is red is 28/99 +4/33 = 40/99 = 0.40404040404...
