Answer: X=1/4 or X=0.25
Step-by-step explanation:
-3+12x
Bring the 3 to the other side to isolate x
12x=3
Divide both sides by 12
x=0.25
Answer: Maggie is 7 years old.
Step-by-step explanation:
Maggie = x years old
Maggie’s brother = 4x - 3 years old
x + 4x - 3 = 32
5x -3 = 32
5x = 35
x = 7
1/5 is the answer. How to slove: You turn the mixed number into an improper fraction which would be 15/4 =, because 4(3)= 12 + 3 = 15 and the denominator stays the same so it would be 15/4. Next, multiply ( the but dont forget to "flip" the improper fraction so it's 4/15) 3/4(4/15)= 1/5
Answer:
It will take 554 years
Step-by-step explanation:
Here, we want to estimate the time when t will be $50
We can rewrite the exponential equation as;
y = 200(1-0.0025)^t
In this case, y = $50 and we want to calculate t
so, we simply proceed to substitute the value 50 for y
we have this as ;
50 = 200(1-0.0025)^t
50/200 = (1-0.0025)^t
1/4 = 0.9975^t
0.25 = 0.9975^t
Take the natural logarithm of both sides
ln 0.25 = ln 0.9975^t
ln 0.25 = t ln 0.9975
t = ln 0.25 / ln 0.9975
t = 553.8 = 554 years
The bike will be $50 in 554 years
