To answer this question you need to first set up the small, medium, large number of cakes as a ratio with a total. From here you will create a new ratio of the correct number of small medium and large Cakes sold using the total 216. The factor would be to multiply by nine. -Step 1 in picture. After this you would read what the relationship is between a medium and a small and the large and the small profits are - Step 2 in picture. After this you would represents the total profit based on the number of small medium and large cakes that were sold. Making this equal to L648.45. To find the profit for one small, you would then divide 648.45 by the 495 you got when you simplify the expression. The answer is L1.31.
Answer: Observational ; does not
Step-by-step explanation: The main distinguishing factor between an experimental study and an observational study lies in the administration of treatment to the participant of the study. In experimental study, some or all the participant in the study are subjected or exposed to a certain treatment and their response to such treatment. ON THE OTHER HAND, Observational study is usually employed when there is a need to gather information on a particular subject matter without directly influencing the participants. In the scenario above, participants were not given any TREATMENT as they were only required to gather information and not to measure the effect of a treatment.
Answer:
x=5 y=-1
Step-by-step explanation:
y=-5x+24
y=4x-21
Since both equations are equal to y, we can set them equal to each other
-5x+24=4x-21
Add 5x to each side
-5x+5x+24=4x+5x-21
24 = 9x-21
Add 21 to each side
24+21 = 9x-21+21
45 = 9x
Divide by 9
45/9 = 9x/9
5 =x
Now we need to find y
y = 4x-21
y =4(5) -21
y =20-21
y =-1
