Answer: 97 stickers
Step-by-step explanation:
Marie has 87 stickers in her collection.
Each week she collects 5 and gives away 3.
The total number of stickers she gains per week is therefore:
= 5 - 3
= 2 stickers per week
In 5 weeks therefore, she would have collected:
= 2 * 5
= 10 stickers
Add that to the original number:
= 87 + 10
= 97 stickers
Theres nothing to see on the screen
Answer:
the difference is 14
Step-by-step explanation:
subtracting 3x2 4x – 5 from 7x2 x 9 results in a polynomial
Subtract 
Multiply negative inside the parenthesis
Now we subtract 4x^2 -3x from the result
14
Answer:
Both of them can be simplified.
Recall that 4 = 2^2.
2^7 / 4^2 = 2^7 / (2^2)^2 = 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
Similarly, 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
The answers to both exercises are 8.
Two numbers are relatively prime if they have no factors in common. In other words, if their greatest common divisor is 1.
7 and 42- both divisible by 7
66 and 77- both divisible by 11
90 and 891- both divisible by 9
Answer would be 16 and 39
