Answer:
x=34
Step-by-step explanation:
x + (x + 11) =79
Combine like terms
2x+11 = 79
Subtract 11 from each side
2x+11-11 = 79-11
2x = 68
Divide by 2
2x/2 = 68/2
x = 34
Answer: The actual height of train = 4.896 meters.
Step-by-step explanation:
Since we have given that
Lina has a scale model of a modern train
Model is created at a scale is given by
1:48
Height of the model train = 102 millimeters
We need to find the actual height of the train.
Since there is direct variation between model and actual height of the train.
According to question,

Hence, the actual height of train = 4.896 meters.
Lets say the final price of the bike is SP plus 13% VAT. So:
1.13 * SP = 6356.25
SP = 5625
Now SP was after 10% discount on Original Price, say MP. So:
0.9 * MP = 5625
MP = 6250
Therefore, the percent of Marked Price above Cost Price is:
(6250 - 5000) * 100/5000 = 25%
4, 8, 12, 16 because they are all multiples of 4 and 2
So, either x or y axis is the same for that intersect point
