The systems of equations that could be used to solve the problem is
5n = 3d
5n = 3d3d + 5n = 4
Given:
numerator = n
denominator = d
Ratio = 3 : 5
Equation 1
n / d = 3/5
cross product
n × 5 = d × 3
5n = 3d
Equation 2
(n + 2) / (d + 2) = 3/5
cross product
(n + 2) 5 = (d + 2)3
5n + 10 = 3d + 6
collect like terms
10 - 6 = 3d - 5n
4 = 3d - 5n
3d + 5n = 4
Therefore, the systems of equations that could be used to solve the problem is
5n = 3d
5n = 3d3d + 5n = 4

I am pretty good at any math and I love a good challenge. What is your question because I'd be glad to help!!!
Answer:
D corresponds to the base.
Ethire C or A corresponds to the height.
I'm sorry, that's all I know. I'm new to this kind of math.
Step-by-step explanation:
If we say that because she bought her materials now she has -50 then she needs to make 215+50=$265 265/17=15,5 so she needs to sell 15
But if we dont take into account that she paid $50 beforehand then 215/17=12,6 so she has to sell 13 poems. Hope it helps
