Answer:
3
Step-by-step explanation:
Write down the expression exactly as it is given.
Now write the expression again, but replace x with 3, and replace y with 6.
Now simplify the numerator using the correct order of operations.
Now divide 9 by 3.
Answer: 3
<u>Answer:</u>
25 weeks will Toby and Marcus have the same number of stamps
<u>Explanation:</u>
No of stamps collected by Toby initially= 10
No of stamps Toby collects every week= 4
No of stamps Marcus has initially= 60
No of stamps Marcus collects each week=2
Suppose the no of week when Toby and Marcus have the same number of stamps are x
Hence no of stamps collected by Toby after x weeks
=10+4x
No of stamps collected by Marcus after x weeks
=60+2x
Therefore to calculate the same of stamps collected by Toby and Marcus
No of stamps collected by Toby after x weeks= No of stamps collected by Marcus after x weeks
10+4x =60 +2x
4x-2x= 60-10
2x=50
x=25
Hence after 25 weeks Toby and Marcus will have the same number of stamps
In this equation y would equal 4 or it could be 1
Answer:
4x^2 - 6x^2 -6x + 3x +3 - 4
Step-by-step explanation:
The terms here involve x^0, x, x^2.
Write the x^2 terms first: 4x^2 - 6x^2;
then write the x terms: -6x + 3x; and
then write the constants: 3 - 4
and so we have, in descending powers of x,
4x^2 - 6x^2 -6x + 3x +3 - 4
