Answer: n=1
Step-by-step explanation:
We have the following expression:
![-\frac{1}{2}(2n+4)+6=-9+4(2n+1)](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%282n%2B4%29%2B6%3D-9%2B4%282n%2B1%29)
Begining by applying the distributive property with the parenthesis:
![-\frac{1}{2}(2n)-\frac{1}{2}(4)+6=-9+8n+4](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%282n%29-%5Cfrac%7B1%7D%7B2%7D%284%29%2B6%3D-9%2B8n%2B4)
Grouping similar terms:
![-n+4=-8n-5](https://tex.z-dn.net/?f=-n%2B4%3D-8n-5)
![4+5=8n+n](https://tex.z-dn.net/?f=4%2B5%3D8n%2Bn)

Answer:
y=5x+350
If Elena spent a total of $1000, she made 130 shirts.
Step-by-step explanation:
Let x be the number of T-shirts. Let y be the amount of money spent.
1000=5x+350
5x=650
x=130
3:1/2 ×(11×4)
=1/2×44
=22m squared(2)
pretty sure double check with the example ur self okey so we make sure
in 1:i think it says to multiply lenght times width (L×W)
so its probably
area=l×w
=6 1/2 × 15 1/2
which when i put in the calculator it gives 45/2
I learned to do KCC (Keep Change Change)
Keep 3 change the sign, and change the 18 to positive.

Answer: d= 21
Answer: 10 m^2.
Explanation:
A = 1/2 (a)(b)
A = 1/2 (4m)(5m)
A = 1/2 (20m^2) = 10 m2.
