Answer: 12 years old
Step-by-step explanation:
10,11,12,12,13,13,14
The middle in these numbers is 12
For the first system, we have
1 - 3x + 3y = -8
or
-3x + 3y = -9
The second equation, however, tells us
-3x + 3y = 13
but -9 ≠ 13, so this system has no solution.
For the second system, notice that multiplying both sides of
4x - 8y = 6
by 1/2 gives
2x - 4y = 3
which is identical to the other equation in the system. Then all point (x, y) that lie on this line are solutions to the system, meaning there are infinitely many solutions.
Answer: $25,500
Step-by-step explanation:
15/100 = 4500/x , we use this proportion to find out how much the entore book deal was. When you multiply 4500 x 100 and divide by 15, it gives you an answer of 30,000. 30,000 is the value of the book deal. The agent gets 15% but the entire deal would be worth 100%. We subtract 15% from 100% to get 85%. 85% is what the author will receive. 85% of 30,000 is $25,500. We find the answer by multiplying 30,000 by 0.15. 0.15 is the decimal equivalent of 15.
I say it has to be b because it would make more sense
