Answer:
![N=2Z-11](https://tex.z-dn.net/?f=N%3D2Z-11)
![\begin{array}{cc}\text{Zac's score}&\text{Natan's score}\\ 6&1\\7&3\\8&5\\9&7\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D%5Ctext%7BZac%27s%20score%7D%26%5Ctext%7BNatan%27s%20score%7D%5C%5C%206%261%5C%5C7%263%5C%5C8%265%5C%5C9%267%5Cend%7Barray%7D)
Step-by-step explanation:
Nathan's score is 11 less than 2 times Zac's score.
Let Z points be Zac's score and N points be Natan's score. then
2 times Zac's score = 2Z
11 less than 2 times Zac's score = 2Z -11
So, N = 2Z - 11
1. If Z=6, then ![N=2\cdot 6-11=12-11=1](https://tex.z-dn.net/?f=N%3D2%5Ccdot%206-11%3D12-11%3D1)
2. If Z=7, then ![N=2\cdot 7-11=14-11=3](https://tex.z-dn.net/?f=N%3D2%5Ccdot%207-11%3D14-11%3D3)
3. If Z=8, then ![N=2\cdot 8-11=16-11=5](https://tex.z-dn.net/?f=N%3D2%5Ccdot%208-11%3D16-11%3D5)
4. If Z=9, then ![N=2\cdot 9-11=18-11=7](https://tex.z-dn.net/?f=N%3D2%5Ccdot%209-11%3D18-11%3D7)
Thus, four other possibilities are
![\begin{array}{cc}\text{Zac's score}&\text{Natan's score}\\ 6&1\\7&3\\8&5\\9&7\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D%5Ctext%7BZac%27s%20score%7D%26%5Ctext%7BNatan%27s%20score%7D%5C%5C%206%261%5C%5C7%263%5C%5C8%265%5C%5C9%267%5Cend%7Barray%7D)
Answer: 5 brownies
Step-by-step explanation:
cookies = 5 x $0.50 = $2.5
$15 - $2.5 = $12.5
$12.5 divided by $2.25 = $5.555
so at the most ella can buy 5 brownies if she buys 5 cookies
2(-11)-19
-22-19
-41
D is the answer
Answer:
n = -4
Step-by-step explanation:
Notice how in the previous examples they all divide by 2? It is the same case here. So now the question is... "what" divided by "2" is "-2".
Let me show you:
n ÷ 2 = -2
if you know your integer math, you should know that...
-4 ÷2 = -2 (this is the correct equation)
