Answer:
n=7 d=8
Step-by-step explanation:
n+d=15 d=15-n
0.05n+0.1(15-n)=1.15
0.05n-0.1n+1.5=1.15
-0.05n=-0.35
n=7 d=8
Answer:
I think that it is D or B from my side
A = bh/2
12= bh/2
bh = 24
We need to find pairs that multiply to 24
Answer: b=3 and h=8

<h3>How to solve the system of equation?</h3>
4x + 5y = -1
-5x - 8y = 10
Therefore,
20x + 25y = -5
-20x - 32y = 40
-7y = 35
y = -5
Hence,
4x + 5(-5) = -1
4x - 25 = -1
4x = -1 + 25
4x = 24
x = 24 / 4
x = 6
