1) 6x-5 = 2x + 7

4x=12 and x =3

2) since PQ//SR, Ange S is the supplement of angle P
 31° + P° =180°, and P° = 149°

3) The kite has a symmetric axis that is y-axis and
the coordinate of E(w,0)

4) The midpoint of WX:. Let M be the Midpoint
Formula to find the coordinates of Midpoint, knowing the coordinates
of W(0,4b) and X(2a,0) is:
the x of M = (x₁+x₂)/2 = (0+ 2a)/2 =a
and the y of M =(y₁+y₂)/2 = (4b+0)/2 =2b, so M(a,2b)

A store sells 4 main types of chocolate bars milk chocolate dark chocolate white chocolate and hazelnut chocolate the store empl
sergij07 [2.7K]
Hi there! The answer is A. 252

To find the percentage of the customers who preferred the milk chocolate bar we need to know two things:

First we need to know the total amount of customers, which is 50.
Second we need to know how many of these customers preferred the milk chocolate bar. This bar is preferred by 28 people.

Now we can fill in the following formula, in order to find our percentage:
\% = \frac{part}{total} \times 100 \% = \frac{28}{50} \times 100 \% = 0.56 \times 100 \% = 56 \%

Now we can multiply this percentage by the total amount of chocolate bars which will be bought (which is 450).
56 \% \times 450 = 0.56 \times 450 = 252

Hence, the answer is A. 252
~ Hope this helps you!

If any two sides and any angle are congruent in two triangles, then the triangles must be congruent. is it true or false?
Mice21 [21]
Well,  It is False. The sides must form the angle, i.e. /_ <- the angle formed, and the two sides must be in this position. its the ASA postulate.


I hope this helps!
