-- these are called same side exterior angles, which means they are supplementary.

x + 9 + 2x + 6 = 180

3x + 15 = 180

3x = 165

x = 55

so, option B.

x=3

Step-by-step explanation:

(x+9)°=(2x+6)°(by alternate exterior angle)

9-6=2x-x

3=x

check

(x+9)°=(2x+6)°

put value

3+9=2×3+6

12=12

LHS = RHS

Solve 729 s-⁵ = 3² (1-s) for S.​
sweet [91]

Answer:

No real solutions.

Step-by-step explanation:

729s^-5 = 729/s^5

729/s^5 = 3^2(1-s) = 9(1-s)

729=9(1-s)(s^5)

(1-s)(s^5)=81

s^5-s^6=81

Because 81 > 0 this means s^6 must be less than s^5. This is never possible as 6 is even so is always positive and is always greater in magnitude than s^5. The only time this isnt the case is when s is a decimal less than 1, but then the difference would be also less than 1 and not 81.

How many pieces of wire 2½ cm long, can be cut from a roll of wire 58 cm long?<br>No links please.​
tatuchka [14]

Step-by-step explanation:

Break it into steps you can better understand

2 1/2 = 2.50cm

You want to take as many 2.50 cm pieces as possible so you cut one off.

58 - 2.50 = 55.5

and another

55.5-2.50 = 53

and so on...

Instead of subtracting like this, we use division

58 / 2.5

when you divide, this tells you how many 2.50cm pieces you can cut from a total length of 58cm

According to the 2010 U.S. Census, there are approximately 8 million people living in Virginia. This is 2.8 million less than 4
grandymaker [24]

Solution: We are given that the population of Virginia is 8 million.

Let x be the population of Nevada.

We are given population of Virginia is 2.8 million less than 4 times the population of Nevada.

\therefore 4x-2.8=8

      4x=8+2.8

      4x=10.8

      x=\frac{10.8}{4} =2.7

The first step is to on both sides.

add 2.8

The second step is to on both sides.

divide 4

The population of Nevada is million.

2.7
