4.5 is the answer because I think you just subtract the two numbers that is given. Because they is asking for the difference
Q = 21
29 - q = 8
First subtract 29 from both sides.
-q = 8 - 29
Subtract 29 from 8 which is -21.
Then flip the signs.
q = 21
Answer:
2y-x= -10
3y-x = 18
Step-by-step explanation:
The correct option is . 2y-x = -10 , 3y-x = 18
one half x − 5 = 1/2 (x-5)
one third x + 6 = 1/3 *(x+6)
1/2 x-5 = 1/3x+6 =y
y= 1/2x-5
y = 1/3x+6
Now,
y=x/2 -5 equation 1
y = x/3 +6 equation 2
By taking L.C.M of the first equation we get:
y=x/2 -5
y= x-10/2
Now multiply both terms by 2.
2y=x-10
2y-x= -10
Now lets solve second equation:
Take L.C.M of the second equation:
y = x/3 +6
y=x+18/3
Multiply both sides by 3
3y= x+18
3y-x = 18
Therefore the system of equations we get is:
2y-x= -10
3y-x = 18 ....
Answer:
D. 5 +6k/n
Step-by-step explanation:
The width of the interval is (5 -2) = 3. The width of one of n parts of it will be ...
3/n
Then the difference between the left end point of the interval and the value of x at the right end of the k-th rectangle will be ...
k·(3/n) = 3k/n
So, the value of x at that point is that difference added to the interval's left end:
2 + 3k/n
The value of the function for this value of x is ...
f(2 +3k/n) = 2(2 +3k/n) +1 = (4 +6k/n) +1
= 5 +6k/n
We played a game four times and got the score as -1, -4, -8, and 10.
To get the final score, we should add all results of all the games together.
Final Score = First game result + Second game result + Third game result + Fourth game result.
Final score = (-1) + (-4) + (-8) + (10)
Final Score = (-13) + (10)
Final Score = -3
Hence, the overall score of all the games would be -3.
