Answer:

Step-by-step explanation:
If P partitions AB in the ratio 1:1, it means AP = ½ of AB, and PB = ½ of AB.
Therefore, P can be said to be a midpoint between A and B.
To find the coordinates of P, use the midpoint formula:
Midpoint (P) of AB, for A(3, 5) and B(1, 2) is given as:

Let 

Plug the values into the formula:



Answer:
b=
−3
/x
Step-by-step explanation:
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2x.
−2bx
−2x
=
6
−2x
b=

Answer:
Amount = £37
Step-by-step explanation:
Let Rose be represented by R.
Let Haydn be represented by H.
Given the following data;
Total amount = £250
Ratio of R:H = 2:3 = 2 + 3 = 5
To find how much Rose earned;
R = 2/5 * 250
R = 500/5
R = £100.
For Haydn;
H = 3/5 * 250
H = 750/5
H = £150
Next, we calculate the amount Haydn gave to charity;
Percent = 42% = 42/100 = 0.42
H = 0.42 * 150
H = £63
To find how much more Rose gave to charity than Haydn;
Amount = R - H
Amount = 100 - 63
Amount = £37
