Answer:
x = 
Step-by-step explanation:
Given
ax = bx + 1
Collect the terms in x on the left side by subtracting bx from both sides
ax - bx = 1 ← factor out x from each term on the left side
x(a - b) = 1 ← divide both sides by (a - b)
x =
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x
7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21
Ni: 7x=7*0.21=1.47 ≈1.5 kg
Zn: 2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg
Check 1.5+0.4+1.9 =3.8 True
Answer:I believe I did this wrong but I got 126,343.75
Step-by-step explanation:
I divided 5000 by 100 to get the percentage then I multiplied the answer by 3.75 for the interest rate then I multiplied that answer by 25 then I multiplied 5000 by 25 and added them together
