Step-by-step explanation:

The fraction Anna saves is given as 19%.

The fraction Laura saves is 1-(17/20) = 3/20 = 15/100 = 15%.

The fraction David saves is 2/(2+8) = 2/10 = 20/100 = 20%.

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.

Well if the <1+<2=180 then you can put the equation as 4x+10+x+20=180. We can simplify that to be 5x+30=180. Minus 30 from both sides: 5x=150; x=30
