The line segment joining the points ( 3,-4) and (1,2) is trisected at the points P and Q . If the coordinates of P and Q are (p
sdas [7]

Answer:

P = 7/3 and q = 0

Step-by-step explanation:

The given parameters are;

The endpoints of the segment are, (3, -4) and (1, 2)

The points that trisect the given points are P and Q with coordinates (p, -2) and (5/3, q) respectively

Therefore, we have;

The first point of the trisection cuts 1/3 of the length from one point and the second point of the trisection cuts 2/3 of the length from the same point

The coordinates of P or Q = (3 - (3 - 1)/3, -4 - (-4 - 2)/3) = (7/3 , -2)

Therefore, given that the y-coordinate value of the derived point coincides with the y-coordinate value of the point P, (p, -2) and there is only one point with x = -2 on the line, we have that the coordinate of the point P is (p, -2) = (7/3 , -2)

∴ P = 7/3

Similarly we have the second point of the trisection, Q, given as follows;

We are already given the x-coordinate value of the point Q as the 5/3 in (5/3, q)

Point Q = (5/3, q) = (3 - 2×(3 - 1)/3, -4 - 2×(-4 - 2)/3) = (5/3 , 0)

Point Q = (5/3, q) = (5/3 , 0)

∴ q = 0.

Your petty cash has a balance of $73.28. Your Center Manager provides you with two receipts totalling $52.29. How much cash rema
Dvinal [7]

Answer:

Cash remaining in the petty cash box = 20.99 dollars

Explanation:

Given that,

Petty cash has a balance of = 73.28 dollars

Total receipt = 52.29 dollars

We need to find the remaining petty cash .

In order to find out the remaining cash, we will subtract total receipt from Petty cash balance.

Cash remain = Petty cash balance - total receipt

Cash remain = $73.28 - $52.29

Cash remain = 20.99 dollars

That's the final answer.

I hope it will help you.

Max was on vacation twice as long as Jared and half as long as Wesley. The boys were on vacation a total of 3 weeks. How many da
GuDViN [60]
Lets say W=Wesley, M=Max, and J=Jared.
So your equations are M=2J, 2M=W, and M+J+W=21days(3 weeks)
So substituting M and W into M+J+W=21 gives you 2J+J+2M=21, substitute M again, to get 2J+J+4J=21 so you get 7J=21 so J= 3 days. Using J=3, substitute in to find M, using M=2J, so M=2(3) so M=6 and using that, substitute into 2M=W, so 2(6)=W so W=12. And 12+6+3=21 to check.

Answer: #20, x = 3

              #21,  x = 1/2

Step-by-step explanation:

#20) x + 4 + x + 2+ x + 5  = x + 3 +x+3+x+1+x+1

3x + 11 = 4x + 8

<u>-3x           -3x</u>

      11= x + 8

  <u>   - 8       - 8</u>

     3   =   x

#21)  12x(5) = 6x + 9 + x + 10 + x + 7

         60x =8x + 26

       <u>   -8x    -8x</u>

         52x = 26

 divide both sides by 52

         x = 1/2
