Answer:
Step-by-step explanation:
In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.
<u>So we should start on the number without variables:</u>
23 and 27
<u>Match them up together and you should find your first equation:</u>
23 - 7
==> -4
So we should have -4 + 8m + 4n - 5m
Now we should combine the numbers with the variable of m:
8m and 5m
<u>Match them up together and you should find your first equation:</u>
<u></u>
8m - 5m
==> 3m
So we should now have -4 + 3m + 4n
<u></u>
<u>Since there are no other variables of n, we are all done:</u>
<u>-4 + 3m + 4n is your final answer </u>
Initially, Alice had 28 sweets and Olivia 12 sweets.
Step-by-step explanation:
First assume that Aunty Joan has x number sweets.
Alice and Olivia shared the x sweets in a ration of 7:3, this means
Alice had 7/10 x sweets and Olivia had 3/10 sweets.
Alice gives 3 sweets to Olivia, Alice will remain with ;
Then the new ratio changes to 5:3 which means Alice will have 5/8 x number of sweets.
Equate the number of sweets for Alice in the two cases, which is
So there were 40 sweets at first
Using the ratio of 7:3 then
Alice had 7/10 *40 = 28 sweets
Olivia had 3/10*40= 12 sweets
Alice gave Olivia 3 sweets, so she will remain with 28-3 =25 sweets. Olivia will now have 15 sweets.The new ratio will be 25:15 simplified as 5:3.

Answer:
- Only Drawing D has KL being a symmetrical segment.
- Drawings A, B and C have no axis of symmetry.
- Tylko rysunek D ma KL będący segmentem symetrycznym.
- Rysunki A, B i C nie mają osi symetrii.
Step-by-step explanation:
English Translation
In which drawing was the symmetrical segment of KL drawn? Which of these letters has no axis of symmetry?
Solution
The attached image to the question is presented in the attached image to this Solution.
Symmetry is a concept where a figure/shape has half of its part being a mirror image of the other part.
About the line or axis of symmetry, the structure or figure can be rotated at right angles or whole number multiples of right angles and the resulting structure is still the same as the one we started with.
Of the 4 drawings, only drawing D satisfies this conditions/criteria. And Hence, it is the only drawing amongst the four with an axis of symmetry.
In Polish/Po polsku
Załączony obraz do pytania jest przedstawiony na załączonym obrazku do tego rozwiązania.
Symetria to koncepcja, w której figura / kształt ma połowę swojej części stanowiącą odbicie lustrzane drugiej części.
W odniesieniu do linii lub osi symetrii, strukturę lub figurę można obracać pod kątem prostym lub wielokrotności liczby całkowitej pod kątem prostym, a wynikowa struktura jest nadal taka sama jak ta, od której zaczęliśmy.
Z 4 rysunków tylko rysunek D spełnia te warunki / kryteria. I dlatego jest to jedyny rysunek wśród czterech z osią symetrii.
Hope this Helps!!!
Mam nadzieję że to pomoże!!!
