Answer:
19
Step-by-step explanation:
3.920(1.018)ˣ = 5.500
- First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403
- Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)
- We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403)
- Then we can divide both sides by ln(1.108) to get:
- Then using a calculator we get x = 18.98 ≈19
Answer:
Sajini = 200
Drea = 225
Step-by-step explanation:
d = amount Drea earned
s = amount Sajini earned
Together they earned 425
d+s =425
d = s+25
The system of equations
d+s =425
d = s+25
I will use substitution to solve
Substitute d= s+25 into the first equation
d+s =425
(s+25) + s = 425
Combine like terms
2s+25 =425
Subtract 25 from each side
2s+25-25 =425-25
2s = 400
Divide by 2
2s/2 =400/2
s =200
Sajini = 200
Now we need to find d
d = s+25
d = 200 + 25
d = 225
Drea = 225
