Answer:
y = 8x
Step-by-step explanation:
a y = 8x
40 = 8*5
40 = 40
This is a solution
Answer:
x = 3
Step-by-step explanation:
For them to be congruent, both sides need to be of equal length. Set them equal to each other and you get 5x-1=3x+5, which equals to 2x=6, so x=3
For this case we have the following data:
31, 32, 32, 33, 34, 35, 35, 35, 35
The median is given by the central datum:
Median = 34
Mode is given by the most repeated data:
Mode = 35
Answer:
Median = 34
Mode = 35
Answer:
21 % increase
Step-by-step explanation:
Lets imagine the sides of the rectangle are 100 & 200 cms.
The area would be 100 x 200 = 20000cm^2
If we added 10% onto each side, the sides would now be 110 & 220 cms.
The area would be 110 x 220 = 24200cm^2
We can now find percentage change:
= 21/100 = 21% increase.
The reason we can just pick random values of sides to do this question with is because we worked out percentage change, which will be the same no matter the proportion of the sides.
Hope this helped! Let me know if you have any questions :)
