Sarah is 8 years older than Tanya. Sarah's age is also 5/4 of Tanya's age. How old is each person?

3 0

S = t + 8
s = 5/4t

t + 8 = 5/4t
8 = 5/4t - t
8 = 5/4t - 4/4t
8 = 1/4t
8 * 4 = t
32 = t <=== tanya's age

s = t + 8
s = 32 + 8
s = 40 <== sarah's age

Solving the equation and something to do with log

Anastaziya [24]

Answer:

m= 1/2.

Step-by-step explanation:

To solve this, we must make the bases equivalent. We can do this by finding the common base which is 5.

We know that 125= 5³ and 25=5², which will help us in this equation. We can rewrite the equation substituting this for the original numbers:

$5^{3(2m)} = 5^{2(m+1)}$ Distribute the exponents to get:

$5^{6m} = 5^{2m+2}$

Now, we can simply ignore the '5' and solve for 'm':

6m= 2m+2

4m= 2

m= 1/2.
