I NEED HELP PLZZZ Josh simplified 4x - 8x / 2 and said the answer was -2x. What was Josh's error? What should his answer have been?\
Answers
This is a trick question Josh did not have an error. If you have 4x-8x in the numerator that becomes a -4x/2.
So then -4x/2= -2x
Josh was not wrong.
I hope this helped!

Answers
Answer:
x=5, y=8. (5, 8).
Step-by-step explanation:
3x+5y=55
5x+4y=57
---------------
5(3x+5y)=5(55)
-3(5x+4y)=-3(57)
-------------------------
15x+25y=275
-15x-12y=-171
---------------------
13y=104
y=104/13
y=8
3x+5(8)=55
3x+40=55
3x=55-40
3x=15
x=15/3
x=5

For the first one, you would have to subtract 5 from 8 which would give you x=3!! that is your answer. For the second one, you would have to subtract 3 from -6 which would give you -a=-9, but were not done here yet, we are going to multiply this by -1 because you can't have a negative variable which will give you a=9. And last but not least, on the third one, you would have to subtract 21 from 30 which will give you c=9. There is no specific formula to do these problems other than to get rid of the "third wheel number".

Answer: Second option.
Step-by-step explanation:
By definition, a Coordinate plane has an horizontal axis, which is called the x-axis and it also has a vertical axis,which is called the y-axis.
Observe in the picture given in the exercise that the point of intersection between the x-axis and the y-axis is the point , which is known as "Origin".
Given a point (x, y), "x" is the x-coordinate of the point and "y" is the y-coordinate of the point.
Then, given the following point:
You can identify that its x-coordinate is:
And its "y" coordinate is:
You can observe in the picture that this coordinates corresponds to the point B.
b. 1/3
c. 2/3
d. 1

The fraction represents how many games Krista's softball team lost out of the 35 games Krista's team played.
To find the percent of games that Krista's team lost, we need to turn the fraction into a percent.
We can reduce by dividing both the numerator and denominator by the Greatest Common Factor of 7 and 35 using 7.
7 ÷ 7 = 1
35 ÷ 7 = 5
Now, we have our reduced fraction.
1 ÷ 5 = 0.2
0.2 × 100 = 20%
Therefore, Krista's softball team lost 20% of their games.
