23.) 21 hrs at $ 11 per hr = (21 * 11) = 231....and u received 91% of ur wages...
0.91 (231) = 210.21
fraction u got : 210.21 / 231 = 0.91 = 91/100 <== I am not 100% sure on
this. I might be making this harder then it looks....u r going to get 210.31 take home pay.....or 91% which in fraction form is 91/100

26B. 17/10 = 85/ x
cross multiply
17x = 850
x = 850/17
x = 50....50 liters of oil <==

26C. 12:9...added = 21

12/21(4200) = 50400/21 = 2400 <== higher cost receives 2400
9/21(4200) = 37800/21 = 1800

What are the coordinates of the point that is one half the distance between A(-1, -2) and B(6, 12)?

MA_775_DIABLO [31]

The coordinates of the point that is one-half the distance between A(-1,-2) and B(6,12) is (2.5,5)

What is the midpoint?

The mid-point lies midway between the two ends. Its x value lies in the middle of the other two x values. Its y value lies in the middle of the other two y values.

Given, $A(6,12) = (x_{1}, y_{1} )$

$B(6,12) = (x_{2}, y_{2} )$

Let M is a midpoint of AB, then

$M(x,y)=(\frac{x_{1}+x_{2} }{2} ,\frac{y_{1} +y_{2}}{2} )= (\frac{-1+6}{2} ,\frac{-2+12}{2} )=(2.5,5)$

The midpoint of point AB is M(2.5,5)

Therefore, the coordinates of the point which is one-half the distance between A(-1,-2) and B(6,12) is M(2.5,5).

Check whether p=-2 is a solution of the equation 7p-5=20 or not ...

Lana71 [14]

Answer:

not a solution

Step-by-step explanation:

Substitute p = - 2 into the left side of the equation and if equal to the right side then it is a solution.

7(- 2) - 5 = - 14 - 5 = - 19 ≠ 20

Then p = - 2 is not a solution of the equation
