Answer:
x+1
Step-by-step explanation:
1.) -2(-x-1)-(x+1)
2.) -2(-x-1) = 2x+2
3.) 2x+2-(x+1)
4.) -(x+1) = -x-1
5.) 2x+2-x-1 = x+1
ANSWER: x+1
Answer:
\left(\frac{\sqrt{78}}{30},\ \frac{\sqrt{78}}{39}\ ,\frac{41\sqrt{78}}{390}\right)
The student is wrong in not putting a parenthesis between 1/3 and x. An equation of a line has a general equation of y = mx + b where m is the slope and b is the y-intercept. In this case, most likely 1/3 is the slope and 0 is the y-intercept. However, writing the equation like that seems like the x variable is a denominator and if that is the case the equation will not represent a line already.
Answer:
The probability that a car chosen at random is not red is 75%.
Step-by-step explanation:
Given that a used car dealer sells SUVs and cars, and of all the vehicles, 60% are cars, and of all the vehicles, 15% are red cars, to determine what is the probability that a car chosen at random is not red you must perform the following calculation:
60 = 100
15 = X
15 x 100/60 = X
25 = X
100 - 25 = 75
Therefore, the probability that a car chosen at random is not red is 75%.
Well, if Tina can make 3 pies in one hour, she have to do 6 pies and she have already 2 so she can have as many pies as Bella, so the answer is 2 hours
