Answer:
RT = 9
Step-by-step explanation:
x-2 + 4x-9 = x+5
5x-11 = x+5
subtract the x from the right side to 5x and the left side x cancels out
add 11 on the right side which cancels out and add to right side
4x = 16
divide 4x by 4 which cancels out and divide 16 by 4
x = 4
take the equation for RT = x+5
yk x = 4 so that makes 4+5 which is equal to 9
Answer:
Sophia now has 39 cents.
Step-by-step explanation:
One quarter = 25 cents
Since Sophia had 64 cents until she spent 25 cents (1 quarter).
So we subtract 25 cents from 64 cents.
Therefore, Sophia now has 39 cents.
Answer:
number of units for cost to be minimum=150
Step-by-step explanation:
y=2x^2-600 x+49000
dy/dx=4x-600
dy/dx=0 gives 4x-600=0
4x=600
x=150
d^2y/dx^2=4x
at x=150,d^2y/dx^2=4*150=600>0
so y is minimum at x=150
Answer: 22.5 kg
Step-by-step explanation:
You did not attach a question, so I'm going to assume that it is asking for the maximum weight of a suitcase in kilograms.
0.99999696 is your answer I am pretty sure.
