Answer:

t= 0

Step-by-step explanation:

Using the rules of logarithms

log x + log y = log(xy)

log_{b} 1 = 0

Given

log_{x} a + log_{x} \frac{1}{a} = t ,then

log_{x} (a × \frac{1}{a} ) = t

log_{x} 1 = t , thus

t = 0

How to solve the question
Scorpion4ik [409]
You have the equations set up correctly. I will use r and b as the variables to make it easier to follow.

12r + 8b = 70
20r + 12b = 110

First let's solve one of the equations for one of the variables.

12r = 70 - 8b

r =  \frac{70-8b}{12}

Now plug that in for r in the second equation.

20( \frac{70-8b}{12})+12b = 110

Simplify

20(70-8b)+144b=1320

1400-160b+144b=1320

-16b = -80

b = 5 grams

Now plug 5 in for b in one of the original equations to find r.

12r + 8(5) = 70

12r  = 30

r = 2.5 grams

So the red marbles weigh 2.5 grams, and the blue marbles weigh 5 grams.

Ethan is 11 inches shorter than 3 times his little sister
PtichkaEL [24]

Answer:

30"

Step-by-step explanation:

We know:

E = 3*s - 11

E = 79"

Setting them both equal:

79 = 3s - 11

add 11 to both sides

79 + 11 = 3s - 11 + 11

Simplify

90 = 3s

divide both sides by 3

90 / 3 = 3s / 3

Simplify

s = 30"
