Alja [10]

Answer:

Look below!

Step-by-step explanation:

1A (fraction): 1/6

1B (decimal): 0.16 (6 continues)

1C (percent): 16.66 (6 continues)

5+15+7+8+10+15=60

10/60 time she got 5

1/6 chance she gets a 5 again

2A (fraction): 1/6

2B (decimal): 0.16 (6 continues)

2C (percent): 16.66 (6 continues)

Yellow: 3/10 chance

Red: 1/5 chance

Blue: 2/5 chance

Pink: 0/20 chance

You're welcome in advance.

3n-8+2(5n+3)=8n+5+4n

DaniilM [7]

<span>3n-8+2(5n+3)=8n+5+4n first I will do the multiplication
3n-8+10n+6=8n+5+4n Now I will simplify
13n -2 = 12n +5 Now I will add 2 to both sides
13n = 12n + 7 then I subtract 12n from both sides
n = 7</span>

What is 2 (log Subscript 3 Baseline 8 + log Subscript 3 Baseline z) minus log Subscript 3 Baseline (3 Superscript 4 Baseline min

Ilya [14]

Answer:

Value of expression in single logarithm is $\log_3\left(2z^2\right)$ .

Step-by-step explanation:

Given expression is,

$2\left(\log_3\left(8\right)+\log_3\left(z\right)\right)-\log_3\left(3^4-7^2\right)$

Now using logarithmic rule to solve the expression as follows,

Applying product rule of logarithmic,

$\log_c\left(a\right)+\log_c\left(b\right)=\log_c\left(ab\right)$

Therefore,

$2\log_3\left(8z\right)-\log_3\left(3^4-7^2\right)$

Applying power rule of logarithmic,

$a\log_c\left(b\right)=\log_c\left(b^a\right)$

Therefore,

$\log_3\left(\left(8z\right)^2\right)-\log_3\left(3^4-7^2\right)$

$\log_3\left(\left(64z^2\right)\right)-\log_3\left(3^4-7^2\right)$

Applying quotient rule of logarithmic,

$\log_c\left(a\right)-\log_c\left(b\right)=\log_c\left(\frac{a}{b}\right)$

Therefore,

$\log_3\left(\dfrac{\left(64z^2\right)^2}{3^4-7^2}\right)$

Simplifying,

$\log_3\left(\dfrac{\left(64z^2\right)^2}{81-49}\right)$

$\log_3\left(\dfrac{\left(64z^2\right)^2}{32}\right)$

$\log_3\left(2z^2\right)$

Therefore value of expression is $\log_3\left(2z^2\right)$

your bank account balance was 235.24 after two checks were cashed each for the same amount your balance is now -45.58 what was t

Inga [223]

Divide the balance by 2. this gives you 117.62. Divide the overdraw by 2 giving you 22.79. Add 117.62 and 22.79 this gives you 140.41. now do the math.
235.24-140.41-140.41= -45.58. so each check was 140.41
