Answer:
Step-by-step explanation: lets say, rajiv has x marbles.
given: aman has 40 marbles
and aman's marbles are 25 more than half of rajiv's marbles.
so, aman has 25 + x/2 marbles
40 = 25 + x/2
40 - 25 = x/2
15 = x/2
15*2 = x
30 = x
thus, rajiv has 30 marbles.
Given
12 meters tall airplane
18 meter shadow of airplane
6 meter shadow of jet
Find the measurement of the jet (y)
Solution
6y = 12 + 18 30
----- --------- ----> y = ------- -----------> y= 5
6 6 6
The answer is 5 meters tall is the measurement of a parked jet.
Answer: $3.10 per gallon
Step-by-step explanation: 9.30 divided by 3
C=2πr=2·π·13≈81.68141
C=81.68
The answer would be: x+2y
First, combine the like terms.
-x and 2x
Now your equation looks like this:
x+y+y
Now combine the y like terms.
y and y and you get 2y
Then you are left with your answer: x+2y
Hope this helps! :3
