Answer: C
Step-by-step explanation:
Since this is an isosceles triangle as indicated by the markers on QP and PR, we know that QS and SR are equivalent.
To find the value of n, we set QS and SR equal to each other.
6n+3=4n+11 [combine like terms]
2n=8 [divide both sides by 2]
n=4
Now that we know n=4, we know that A is incorrect. What we can do is use the value of n to solve for QS, SR, and QR.
QS
6(4)+3=13
Since the length of QS is 13, we know B is incorrect.
SR
4(4)+11=27
Since SR is 27, C is a correct answer.
QR
13+27=40
Since QR is 40, the only correct answer is C.

Answer:
40
Step-by-step explanation:
The bread is 90.
28% is cookie
Then 72 %is bread and cake
Sum of bread and cake is 360
1%is 5 so cookie is 140
If sell 40 bread. Bread left is 50. Cake left is 150
Then cookie must be left 100 because the ratio of the no 1 is =to 50
Then need to sell 40 cookie so the ratio will be
50:150:100= 1:3:2
