Let's say you had two boxes of cereal labeled A and B. Also let's come up with a hypothetical situation that...

  • box A costs $2 and weighs 10 ounces
  • box B costs $3 and weighs 20 ounces

The question is: which is the better deal? By that I mean which is cheaper per ounce.

-----------------------

For box A, we have this ratio

2 dollars : 10 ounces

If we divide both sides by 10, then we end up with

2/10 dollars : 10/10 ounces

0.20 dollars : 1 ounce

20 cents : 1 ounce

This tells us that the unit rate for box A is 20 cents per ounce. In other words, 1 ounce costs 20 cents or each ounce costs 20 cents.

-----------------------

Do a similar thing for box B

3 dollars : 20 ounces

3/20 dollars : 20/20 ounces

0.15 dollars : 1 ounce

15 cents : 1 ounce

So box B costs 15 cents per ounce

-----------------------

In summary,

Box A's unit rate is 20 cents per ounce

Box B's unit rate is 15 cents per ounce

Box B is the better deal since it's 5 cents cheaper per ounce.

Answer:

The mid-point of the given line segment is:(5.5,-6.5)

Step-by-step explanation:

let us consider two points A and B with coordinates (a,b) and (c,d) respectively.

let C be the mid point of A and B then then the coordinates of C is given by (\frac{a+c}{2},\frac{b+d}{2}).

in the given question (a,b)=(9,-8) and (c,d)=(2,-5) so the mid point of these two points are (\frac{9+2}{2},\frac{-8-5}{2})=(5.5,-6.5)

Hence, the coordinates of the midpoint of the line segment with endpoints B(9,-8) and C(2,-5) is (5.5,-6.5).

x=26*3=78 p.
2) if (-2) ⇒ -3*(4)=-12 ⇒ answer: (-2;-12)
if (-1) ⇒ -3*(1)=-3 ⇒ answer: (-1;-3)
if 0 ⇒ -3*0=0 ⇒ answer: (0;0)
if 1 ⇒ -3*1=-3 ⇒ answer (1;-3)
if 2 ⇒ -3*4=-12 ⇒ answer: (2;-12)
