Answer:

11. 16x +(9x+5)= 180

25x + 5 = 180

25x= 175

x= 7

If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.

112 + 4y= 180

4y = 68

y= 17

Step-by-step explanation:

12. 6x - 11 + 2x - 9= 180

8x - 20= 180

8x= 200

x= 25

6(25) - 11= 139

20y + 19 = 139

20y = 120

y=6

Given logbM=3.2 logbN=-1.5 and logbP=2.4 find the value of logb(m^2N/p)

artcher [175]

The formulas:
$\log_a (xy)=\log_a x + \log_a y \\
\log_a (\frac{x}{y})=\log_a x - \log_a y \\
\log_a (x^n)n \log_a x$

Expand the expression:
$\log_b (\frac{m^2n}{p})=\log_b m^2 + \log_b n - \log_b p= 2 \log_b m+\log_b n - \log_b p$

Plug the values into the expression:
$\log_b m=3.2 \\ \log_b n=-1.5 \\ \log_b p=2.4 \\ \\
2 \log_b m+\log_b n - \log_b p=2 \times 3.2-1.5-2.4=6.4-3.9=2.5 \\ \\
\boxed{\log_b (\frac{m^2n}{p})=2.5}$

What is the percent decrease from 95 to 68 round to the nearest percent

Setler79 [48]

The decrease is (95-68) = 27 .

As a fraction, the decrease is 27/95 of the original amount.

To change any fraction to a decimal, do the division:

(27) divided by (95) = 0.2842...

To change any decimal to a percentage, move the

decimal point two places that ==> way:

0.2842... = 28.42... %Answer:
